Normally we think of bad design as consisting of laziness, mistakes, or school-boy errors. We refer to these sorts of design patterns as Antipatterns. However, there’s another kind of bad design pattern, one that’s been crafted with great attention to detail, and a solid understanding of human psychology, to trick users into do things they wouldn’t otherwise have done. This is the dark side of design, and since these kind of design patterns don’t have a name, I’m proposing we start calling them Dark Patterns.
I’m preparing a short talk on this for the UX Brighton Conference in September, and I need a bit of help coming up with some examples. Here’s a taste of what I’m talking about:
- Low cost airlines that put insurance in your basket without you asking.
- Social networking sites purposefully make it hard for you to shrink your social graph or move your content into private realms. I’m looking at you, facebook.
- Email sending systems that require you to log-in (using a long forgotten password) in order to unsubscribe. (This is actually forbidden by the revised CAN-SPAM 2008 rules, but it’s widely ignored)
- Systems that ask for your email / twitter credentials on the grounds of finding you friends, but then send messages as if they are directly from you, without your express consent.
- Supermarkets (in the real world) that prevent you from comparing products on price, by putting items in different sized bundles.
Can you think of any good, contemporary examples to go with this list? Add your suggestions in the comments below. I will, of course, credit you in my slides.
To be clear, I’m not looking for outright scams (which are clumsy and easy to identify), I’m looking for techniques used by above-board products and services that trick users into doing things.
Free trial! (if you give us your credit card info first. But you’ll remember to cancel, right?): see Amazon Prime, MobileMe, Experian CreditExpert.
Some obvious ones :
Pre-checked boxes on sign up with messages like: “Uncheck this box if you don’t not want to receive spam from us”
Bundling toolbars and other apps inside another applications install process and hoping the user will not notice.
Games which require you to post a message to Facebook/twitter in order to progress in the game. A nasty “spam your friends” practice.
9.99 is not 9 is 10
Not sure if this counts, but websites that make it super easy for you to sign up online 24 hours a day, but require you to call up during inconvenient business hours to cancel. e.g. creditexpert.co.uk
hi Harry,
The google buzz fiasco got my goat – trying to switch it off was a nightmare, but ‘hiding’ it was all really well placed.
Not sure if this was a ‘dark’ pattern or a matter of deliberate incompetence.
Lou.
Sites that require you to click on the FB “Like” button before they will show you their “on sale” items.
@martin That’s a variation of the CPA / CPL scam (cost per action / cost per lead). whereby a site owner forces you to do something that makes them money, before giving you something “for free”. With Facebook’s like button, it’s not quite so bad – more grey hat than black hat.
The “offers subscription” you get signed up to as they know you won’t read the fine print when you say yes to a “£20 your next xxx” offer.
I got stung by this one, and they start taking money out of your bank account… shocking behaviour!
Ringtones on mobile phones that sign you up to a £4.50 a week service…
There are so many! Ouch, no wonder people get wary of using the web these days.
@Nina I’ve just had that exact experience with Microsoft Xbox live. Easy to sign-up online, but to cancel you have to email them, then have you call you back, go through a telephone security process, then a tedious exit questionnaire.
Amazon’s ‘buy this bundle for ££’ that makes it seem like a saving when actually it’s just the normal price.
eg: like this.
Ticketmaster! At the end of a transaction, the button you see is a big “Continue” button. If you push it you sign up for something. In actuality, you are done with your purchase, and there is small link at the bottom of the page that tells you this.
Have you seen Dan Lockton’s “Design With Intent” toolkit? The machiavellian and security lenses in that would almost certainly have some good examples for you…
http://www.danlockton.com/dwi/Main_Page
When supermarkets display a price above the product – but the price is for a smaller sized item than the one its displayed with. E.G. the sign says “Cornflakes 3 euros” (huge 3 euros, and in tiny writing it says “for 250g pack”) but the sign is displayed with the 500g packs. So when you get to the till its actually 5 euros.
Also the way they keep moving the location of where items are stored – so you have to cover the whole shop looking for the one thing you wanted, but you will most likely buy other things while looking.
Also the way they place sweets and kids DVDs at the tills, to get kids to hassle their parents at checkout time.
I could go on.
Flickr: in order to sign up you have to have a Yahoo ID. Turns many people off signing up to Flickr so may be an own goal for Yahoo.
Enjoyed your article and it seems like a good topic for a talk. It reminds me of the similar concept of “Slanty Design”, where architects create purposefully uncomfortable seats, areas, objects to dispel loiterers. Learn more here.
@Cennydd: “Free trial! (if you give us your credit card info first. But you’ll remember to cancel, right?): see Amazon Prime, MobileMe, Experian CreditExpert.”
I agree with most of your examples, but I don’t think that Amazon Prime should be included in a list of bad apples. They make it VERY clear (at multiple points throughout the sign-up process) that you’ll be charged if you don’t opt out, and (more importantly) they allow you to opt out of the paid continuation at any point, while still continuing to use the free trial.
Last time they offered me a 2 month trial of Prime, I accepted the offer, and then immediately logged in to my account and selected the “Do Not Upgrade” button under the Prime section. Easy-peasy.
You could pick pretty much any element of the Ryanair website, but a particular favourite of mine, if you could call it that, is the way they subtly force you to buy travel insurance. The question is labelled as “Buy Axa travel insurance”, but the select field has a default value of “select country of residence”.
Buried in the middle of the options, which are almost in alphabetical order, is the option “No travel insurance required” – between Latvia and Lithuania!
I ran some usability testing with this site and a number of similar sites for a client of mine (not Ryanair) and almost every participant simply accepted they had to buy travel insurance, because they were blind to this option.
Horrendous, immoral, but quite clever at the same time…
Wow, the Ryanair example is corker! I’ve screen-grabbed it here in case anyone else wants to see. I’ve also just discovered that Flybe charges you £6 on top of the advertised fare for the privilege of having a seat (which you only find out after 5-10 minutes of attempting to make a purchase). Do they do standing-room only fares, I wonder?
Oh the Flybe of doing it is absolutely and utterly warped – well spotted Harry – and thanks Lee for the screengrab, precious
Great article, now on to instill some good ethics into the clients
I’ve always called these people the “Evil UCDers”
Travelocity got me the other day. They also add on travel insurance automatically. They put it in my total. It took me several minutes to notice the link to remove it was actually way down on the screen under several under areas of content and text. So annoying!
I completely agree about the pre-checked boxes to sign up for things and the Continue button, e.g. for Ticketmaster.
It seems like I run across things like this all the time… but I can’t think of additional, specific examples right now to share!
Evil Design is everywhere.
Clicking on a job listing on a Monster email and getting a full screen “special offer” with a small, subdued “no thanks” button to continue to the job listing.
http://www.travelzoo.co.uk lists far too many hard sell travel agencies in it’s deals list.
These agencies advertise bargain holidays – BUT you have to call to book. Once on the phone – the cheap deal has gone and then the hard selling of overpriced holidays begins on your bill.
Last year I tried to book a Holiday through the ‘deals’ on travelzoo and found it was exactly the same pattern (deal has expired + hard sell) from several different deals and several different agencies.
These same ads continued to run weeks after my phone calls.
You should check out “Usability for Evil” http://usability4evil.wordpress.com/
The site was started by Chris Nodder to support his UPA conference presentation in 2008 on the theme of doing evil with design. His mission and I quote “Discover purposefully designed interfaces which make users emotionally involved in doing something that benefits you more than them.â€
Brilliant talk.
Making ads that look like UI elements (e.g. buttons) just to be clicked. Can’t really recall a page right now but I’m sure somebody else will ;)
The FlyBe example is just bad usability. What they are trying to do is get you to pay more for pre selecting a seat. If you don’t touch the box you don’t get charged more. But it ain’t clear.
Joshua Brewer had a great example of a quiz that tricks you into sending out a tweet in his post on Honest Interfaces:
http://52weeksofux.com/post/475093156/honest-interfaces
@Dan Newman: “I agree with most of your examples, but I don’t think that Amazon Prime should be included in a list of bad apples.”
Fair point. I’m actually very happy with Amazon Prime and you’re right; they’re clear about their policy. However, it does bug me when sites do this and claim it’s because it makes “it easy for customers”. What arse. The truly ethical solution is to give me a free trial and then ask if I want to continue, rather than presume my consent.
bit grey but (maybe) worth mentioning. On the Wired iPad (frame) app struggling to differentiate between content and ads?
The oldie-but-goodie:
Redirect-so-that-the-back-button-does-not-work.
You click back, and it hits the page that immediately bounces you back to where you were.
ALSO:
Many, many sales websites disable all buttons and options once you’ve started down the “Check out” path. Nav and subnav disappears, etc. This is to reduce the chance you’ll abort before completing the checkout process.
ALSO:
trialware that keeps menu items visible/clickable but brings up the “only in the full version.” This is actually more “light” than you’d think because it’s explaining the context behind the otherwise-disabled control (disabled controls don’t explain why they’re disabled, usually. One might think an option might at some point become clickable if only the right conditions are met)
I know I have more. I just know I know. :)
A dark pattern is Ad-Sense ads served as site search results (which by definition will generally be more relevant than anything the site’s actual search can return) – or even more devious is Kontera – serving ads as seemingly helpful annotations to a site’s text.
I’m going to have to fight that battle soon with a client….they also remove all navigation in the checkout process, to avoid drop-outs.
It doesn’t work anyway – people just either type a new URL in the address bar, close and re-open the browser, or anything else that gets them what they want. i.e. away from buying something they now don’t want to buy…
Just came across a mildly evil design – 123-reg.co.uk and registering domains. If you search for a domain, it automatically selects several of the available domains (even if you include the TLD in your search.) So if you just click ‘add to basket’ it adds several domains, not just one.
They do make it easy to then remove the extra domains, but I find this very annoying and it’s a bit of extra selling I could certainly do without.
One airline site I used http://airnewzealand.co.nz (today actually!) let you save $NZ100 with a discount code. The problem was that if you didn’t go through their special savings page, you’d go right through the process only to end up on the end page and realise there was no input area for the promo code (which is normally what you’d expect)! Luckily if you cancelled and went through the proper funnel it retained most of the info, but still, I nearly paid $100 more than I needed to!
godaddy.com and tigerdirect.com both add things to your cart without asking, or have in the past. I don’t know about now, haven’t used either in at least a year because of the above.
This example of a voting ballot paper isn’t at all contemporary, but it’s one of my favourite examples of using contrast for evil:
http://en.wikipedia.org/wiki/File:Stimmzettel-Anschluss.jpg
I think the darkest, most evil, pattern of all was the AOL sign up process way back when they offered a ‘free’ service whilst taking credit card details upon sign up.
Once the trial had expired, money would automatically be drawn from your account regardless of whether you used the service or not. To make matters worse it was all installed via a CD, making it truly difficult to remove all the software.
An online service with virus-like difficulty of removal. Absolutely horrible and a disgrace. You can find it as a design principle for Cognitive Dissonance in the book Universal Principles of Design
Still leaves a bad taste in the mouth!
‘Evil UCDers’, ‘Evil Design is everywhere.’
Do you not have a responsibility to your clients too?
As a vocation user experience / usability sits right on the fence in terms of ethics.
Plus it’s not just users that get the rough end of the stick how about great UX reducing the number of call centre staff that are needed when the website suddenly gets so lovely and easy to use?
@ Walt Buchan – very true, I’m sure AOL kept an entire town in jobs with their clandestine credit card screw – speaking to all the customers who were completely dissatisfied with their customer service.
The service was a cynical way to deceive people. In that way it was wrong, simple as that, you simply can not defend the blatantly misleading.
Zynga and other Facebook games and quizzes that trick users into subscribing to overpriced and worthless “services” with recurring monthly fees that are very difficult to cancel.
iPhone games that trick kids into adding worthless images to the game, then charge the parent’s iTunes account for tens or hundreds of dollars.
A recent example of altogether bad UX that comes to mind is facebook’s instant personalization. It opted-in every user by default, and needed a few clicks and reading to be disabled completely: http://mashable.com/2010/04/25/disable-facebook-instant-personalization/
Paypal defaulting to a registered bank account (and providing no way to change that), once you’ve registered a bank account.
(Since they charge the same for payments, and bank debit is free compared to credit card charges)
Wow, where to start – I find what I called ‘anti-usability’ (I like your term better!) very interesting. Here’s a list of ones I’ve found quite prevalent:
1. Alternate radio buttons, one YES not to go on the mailing list, the other NO I do want to be contacted by third parties, etc.
2. Being asked to fill in a ‘simple’ questionnaire to get free stuff. The questionnaire in question then turns out to be an endless tunnel of personal data capture.
3. Hiding telephone numbers, trying to drive people to use email, I’ve even seen (today, on a reputable company’s site) a phone icon which just links to an email form!
4. Cancel My Account button leads to a page that simply gives you a telephone number for a ‘customer service team’ (this one relies on inertia on my part, and it works!)
5. Deliberately making it hard to buy something online so I am forced to physically go to the shop, where presumably I am likely to also buy other things
One thing that one cannot fail to notice is that all these patterns rely on coercion, and desipte the instincts of aggressive salesmen, they are all less productive than genuinely persuasive techniques, which do not result in the customer feeling a sense of a resentment.
This fairly notorious blog post makes the point rather well: http://bit.ly/d8DvLt Who really ever expresses pleasure at the thought of having to fly with Ryannair?!
I noticed this in my tab for this website:
Your website favicon is a ’90’, so this article reads:
90 Dark Patterns: dirty tricks designers use …
But I only see 5 examples! ;)
I’m sure this is a funny coincidence, but I did find it amusing! It’s hard to design for everything, and it is often difficult to determine if the design just missed that aspect, or if it is in fact malicious.
Mall Parking lots (easy to get in, hard as hell to get out).
EULA agreements (in order to use a product you must accept their terms, whatever they may be:
http://www.joystiq.com/2010/04/16/uk-game-retailer-claims-7-500-souls-with-a-legal-agreement-prank/ )
Every TV commercial ever (especially ones that show happy people for products that are not related to happy people)
At the risk of incurring wrath, iPhone/AppStore business model.
VideoGame Downloadable Content at Launch (pay $60 for a game, but if you want all of it pay another $5-$15 right away)
VideoGame Pre-Order Downloadable Content Exclusives (you only get to use this item if you pre-ordered the game at GameStop)
Launching 3D TV before launching OLED TV’s (because they are trying to milk current tech as much as possible before allowing actual innovation)
Well thats all off the top of my head, hope it helps! :-) Liked the article, and I think that “Dark Design Patterns” are everywhere if you look closely enough. I think people stopped noticing the ones that they are used to falling for (80 years worth mass advertising has made it a *subtle* art). Again Good Luck on your talk!! :-)
Not sure if this counts but buying movie tickets online the total is displayed before they assess service fees. You have to enter credit card information before the actual total is displayed. Fandango.com does this.
Yelp or AdWords model takes at least a glancing blow at the Dark Patterns concept.. depending on how much the ads look like results.
The US bus company Greyhound apparently has set up their online ticket purchasing system in a way that many tickets “can’t be found” after being purchased. The passenger is then forced to purchase another ticket and Greyhound will not refund the money from the first ticket.
Greyhound books 2x the revenue on that one.
Supposedly there is a way to get a refund if you spend a month jumping through hoops, but the traveler who wrote the following account finally had to have charge disputed with his credit card company. See:
http://www.planningforfailure.com/post/753812919/greyhound-knows-how-to-fail
If average Greyhound passengers were more familiar with the law, I’m sure a class action lawsuit would result.
Walgreens and most supermarkets I shop at default to debit now when I swipe my card, and ask my PIN without prompting “debit or credit?”.
To use credit, you have to press “cancel”, which wouldn’t be the first thing to come to your mind.
Nowadays, when I don’t see directly see that kind of stuff, I’ll search for it: “No way they are letting me check out without upselling me, I must have checked something I wasn’t supposed to or I must’ve bought the wrong thing”.
The one I hear most talked about is casino design which shuns clocks or windows to make it inconvenient for you to remember there is a world outside.
Actually, see http://casinogambling.about.com/od/moneymanagement/a/control.htm because casinos are pretty much masters at this.
The clocks thing isn’t graphic design per se, but it similarly reflects the sinister motive in the design of an atmosphere (which is really an aspect of your interface with the gambling games).
I’ve seen opt-out pages say things like:
“Are you sure you want to cancel your subscription?”
[cancel] [ok]
Because “cancel” is in the question and the answer, it’s initially unclear if “cancel” undoes your unsubscription attempt, or if it cancels your subscription.
Facebook keeping your data for two weeks after deleting your account. Facebook providing a “deactivate account” option that doesn’t do anything. Facebook asking me for no reason to verify my account by identifying friends in photos (helps them get everything tagged). Facebook using people’s children in advertisements.
Maybe your talk can be just on Facebook alone?
You must put interactivity and animation on your list. If a designer can create an intriguing method of navigation and/or theme in a website, it can attract users to explore and interact with content.
Custom avatar creators are another trick that attracts users. You can find feature websites that let you create yourself as a South Park, Simpsons, and just released, Mad Men character. The ability to create your likeness in a digital avatar will attract people to spend way more time with a product or brand than they would have otherwise.
airitalia had a cookie to bump the price of subsequent searches to the same destination. (very few buy on the first hit)
Only offering a form for contact, not an actual email address. A form is a good idea if you’re not using your own computer, for example, but for something important I’d want to send it from my own email client to make sure I had a copy (because you can’t be sure which forms will mail you a copy!). Both is good; I think seeing real contact details also builds trust even if you don’t use them.
Um how about downlaod websites like download.com which shoes tons of download links like “download your file here” or “download xxx” which is just an ad. The link is just below the ad which is “Download Now”.
Video games hit a big low. The downloadable content is a multi-black hat problem. One comment already illustrated some but let me itterate everything.
1) You buy the game for $50 for a PC, $60 for a xbox 360/ps3. The only thing to get for xbox/ps3 is that you can’t pirate it as easily as on the PC. Usually the PC version even supports a xbox 360 controller plugged in with zero config and out-of-the-box. And usually PC version can look better.
2) Downloadable Content (DLC). You buy the game for 50/60. Now you also have 5-30 dollars more in downloadable content. And if you seen dragon age: origins DLC you will realize that the total worth of all the DLC is maybe MAYBE 10 dollars.
3) More DLC goodies. DLC is not transferable when you sell the game. So the 5-30 dollars you spent is now GONE, has no value, for you or someone buying game form you since once you sold the game, you own the DLC content, not the purchaser, and you can’t use it since you don’t own the game, and the purchaser can’t use it since he does not own the DLC. Wooh doubly-screwed.
4) More DLC goodies. DLC costs microsoft points. You buy 1000 ms points for $12.50. DLC usually costs 800 ($10) or 400 ($5). What happens to the other 200? Oh thats left over so that you have to keep buying points. you wind up spending 50 dollars or so to not “Waste” money. Or you can spend those points on icons. REALLY, MONEY FOR ICONS I CAN DOWNLOAD OR MAKE?! But hey it would not be evil otherwise. Another example is League of Legends. Download the client to see the Riot Points prices. You guy 1000RP, 5000RP, I forget the exacts but you buy large round numbers. However prices are like 375, 955, etc. Basically really nice ways to always have some RP left over.
5) Special Accounts. So basically your game even for xbox comes with a game code. You register the game code and get free DLC. Wooh yay more DLC goodies. Naturally the DLC does not transfer but wait the code comes with another HEAVY price. Basically to play multiplayer you need an account, not with xbox live, but with the company. When you sell the game, even though the game was transfered between owners, the mplayer is not, and the new owner must pay 15-25 dollars for the mplayer capabilities, this is in addition to the $60 per year they pay for xbox live and such, and in addition to the used game itself.
6) Seller Tactics. Gamestop was sued recently because they would sell a used version of a game with the (5) mplayer restriction for say $45, now the new game is $60 and the person winds up really paying the same or higher price for a used game then the new game and does not get the free DLC.
Here in Australia supermarket chains are forced to display ‘unit’ pricing on products, usually in the form of price/100g, or price/piece.
So now it’s easy to tell if the 550g tub of butter is a better deal than the 275g tub.
Advertisements designed to look like functional UI elements. You see these a lot on file hosting websites (i.e. mediafire, yousendit). The webpage is designed for someone to be able to download a file and right above the actual download link is a banner ad shaped like a download button.
Not sure what you mean by the supermarket one. Don’t most also list the unit price, e.g. $/liter, $/gram, etc?
What my local giant does that bugs me is put tags that look almost exactly like the “sale” tags, but they say “Save 50c over Safeway”. By the time I figure out it’s not actually on sale, I already want the item, and get it about 50% of the time. Grrr!
I noticed one of these sneaky design patterns at a gas station recently. The cheap gas to expensive gas left to right pattern is basically a rule, but I went to one station that switched it up and put their most expensive gas in the position that cheap gas normally is in, and designed it to look like a cheap gas option. I only noticed it because their pay at the pump system was so poorly designed that I spent longer looking at the pump then I should have.

I caught Walmart in a little fraudulent pricing scheme http://blog.portal4canada.com/wal-mart-bought-my-silence-for-10-sort-of/
Basically what they did is put a sales sign up saying the price was $10 off the regular price but I found a price sticker on the product with the sale price as the regular price.
I love the name “dark patterns” – that is exactly what it feels like.
T-Mobile has a check box during payment that looks just like the “I agree” check box, except it is to “enroll in automatic payments”. I checked that box by accident once when they’re website was failing and I had to go back. They charged me for 2 months on the spot and my checking was overdrawn. I was not paying late. I simply checked the wrong box – the box that looked like “I agree to terms”…
That’s DARK…

Ooh~! Another one – this, I admittedly KNOW I am walking in dark territory when I’m there, but it is a STUDY in dark patterns – the checkout process at Vistaprint~!!! The prices, deals and percentages change WHILE you’re going through checkout! You can get some great deals there, but must be EXTREMELY CAUTIOUS through checkout. Kings of dark patterns, imho.
Anita @ModelSupplies
How about selling the same basic model at different stores as different models? This happens for mattresses, carseats, and a bunch of other goods.
Restaurant menu designers have their own set of patterns to steer people to higher-profit items and away from concentrating on price, amongst other things. I just did a quick search and found this article on Time about it as a primer: http://www.time.com/time/magazine/article/0,9171,1200775,00.html
Pop up adverts that put an action that forces you to go to the advertised site in place of a close button on the top right! Swines! :)
I love the oldies like:
Nothing Works Faster (meaning they all work about the same speed. you’ll see this alot with pain relievers)
Baked Fresh Daily (but may be brought to you once a week. I think it is impossible to bake stale.)
All Natural Ingredients (Maneure is natuaral but I don’t want it in my Ice Cream)
9 out 0f 10 recommend XYZ (which 9 out of which 10)
Then there is the layout of Grocery Store. Ever notice the items you need to purchase like milk are in the back corner. This is so that you will walk through the store and see other items you want to buy.

While we’re on the subject of airlines and pricing… I’ve always found that I feel ripped off by the end of the easyjet process.
I don’t remember any tricks on the way, but it generally feels like there’s no way you could fly practically for the advertised price, and the checkout process is a progressive set of additions to the cost. The time you’ve put in discourages you from going through the same set of hoops with another airline.

Pretty much anything that Godaddy.com does. You have to wade through 3 screens of opting out before you can actually purchase anything and then even more once the purchase is complete…
ex.
1. you bought the .com but you need to secure the .net, .org, .info, etc…
2. you need private registration
3. insurance (or something similar)
4. hosting
and many more…
Another one (sort of mentioned above) I remember having this at a mattress store.

Pre-installing all kinds of programs that you don’t need on a new computer which take up space and run in the background slowing down your computer.

This is a major issue as some of my friends have 1000s of ‘friends’ who might be of fishy characteristics.
I also agree with Ryan Air being a giant dark pattern, etc.
> Pre-checked boxes on sign up with messages like: “Uncheck this box if you don’t not want to receive spam from usâ€
And furthermore, having such boxes re-check themselves if the form reloads due to an error (e.g. mismatched password, unavailable username, missing required field).

How about the godaddy up sell? especially the default 2 year registration period.
or the recent world cup Toshiba promo “free tv if your country won”
The Pirate Bay has a big download button on its torrent pages that actually is an ad. The download link is much smaller.
Have you seen “The Clear War” on Dustin Curtis’s site?
It describe a case when a UX consultant was asked to design something to intentionally deceive the recipient of an online gift card.
What a list! I learned of it in response to my post last night on some recent travel experiences with
1. easyJet – not clear that it’s double baggage charge when paying at check-in; and
2. Europcar – no warning at time of booking that even though you’ve pre-paid for ‘damage waiver’ you’ll be hit with a substantial ‘super damage waiver’ fee to remove liability for the insurance excess; or that child seats will be rented at more than 4 times their retail price) http://sdj-pragmatist.blogspot.com/2010/07/end-of-cheap-travel.html
Hi everyone, thanks so much for the huge number of detailed comments! Sorry for the delay in responding, I’ve been on holiday. As well as the talk I’m doing at UX Brighton in September, I’m also putting together a small pattern library: http://darkpatterns.org. It’s work in progress (currently unskinned) – I’d love some help naming the patterns, coming up with examples, and so on. I’m intending to credit everyone who has submitted a suggestion here, I just haven’t got around to it yet. So, if you fancy it, check out darkpatterns.org and give me some feedback.

This one is somehow similar to the one you mentioned in your post about airlines:
Ryanair hides the option of “no insurance needed” right in the middle of the drop-down element where you select your insurance country. Just to make to make you hard to find this option:

I worked on an account when the client requested all the optin boxes to be selected by default but then hidden… Very unhappy about having anything to do with that one. A fairly major player in its field, no UK based btw.

A real-world example, but it may have its online equivalents: get less and less for the same price. I noticed this over my cat’s lifetime on a leading brand of cat litter, that would run a promotion every once in a while to pull this off. I forget the exact numbers, but say the original price was EUR 10 for 5 kg of the stuff. They would then run a 10% free promotion for the same 5 kg priced at EUR 10. And after the promotion, you’d get 4.5 kg for the same EUR 10. Promotion after that it was 4 kg for the same price etc.
Making bottles (for detergent etc.) odd shapes or with various exotic caps so that it’s very difficult to get the whole volume of the product out. Obviously makes you buy again sooner than you thought!
Very interesting examples indeed!
I don’t feel any anger towards these sneaky techniques though; if I am on a site that tries it on… they just don’t get any of my money. Ever. I also badmouth them to anyone that will listen, and tweet about their sneakiness. More and more companies are keeping an eye on what’s being said about them online, so maybe one day soon they might pay attention and change their approach.
The same goes for sneaky techniques being used in physical retail premises, eg. Making you walk through the entire store to get to the section you want to go to (Ikea), constantly moving the location of items so you have to wander around looking for stuff (Sainsbury’s Locals), etc.
The Ladders.co.uk – advertise jobs for £50k plus only, then charge you to access them and it is difficult to unsubscribe but with it being illegal to charge jobseekers in the UK this US firm has a page with a tiny tick box which is hard to find with “tick this box to apply for jobs for free” but unfortunately very few people realise this and pay to this unethical firm who sweep the internet for jobs from firms that have actually expired. Sharp practice indeed and these sharks set up here just as unemployment started rising!
Maddie, looking at TheLadders.co.uk now, it seems they’ve changed their design since you last checked. Do you have a dated screengrab?

1. “Upto 50% off”
2. “Limited time offer”
3. All ads are dark patterns, unless provided behind an opt in link (titled something like “View related products”). Online ads are clicked on by a small fraction of users, and do not justify using the majority of users’ attention.

Decentish service, though after you submit your corrections to the credit report, the creditors will ask you to submit paper proof of the error, so it’s kind of useless. It’s good if you have a hard time understanding
Trying to cancel is SO HARD. You go to the membership page, two options, regular and premium. Then you go to the cancel page, and go through 6 or so different pages trying to trick you into staying with the service, only to come to a dead end! It says “call here during 9-5 (when I’m working) to cancel your subscription.”
The lady I talked to on the phone BOTH TIMES I tried to cancel went on about trying to keep me on. They “forgot” to cancel me the first time, and switched my membership instead. Then the second time I got a little terse and received an email confirming that I’m cancelled. We’ll see on the next billing period.

“Alternate radio buttons, one YES not to go on the mailing list, the other NO I do want to be contacted by third parties, etc.”
Great – never seen this and I hope I´ll never visit sites using this trick.
Happy New Year!
Next.co.uk makes it almost impossible to not sign up to a credit account with them. They offer their catalogues at a price cheaper than the delivery cost to lure you in, the ‘pay now instead of signing up’ button isnt even a button its a link, hidden in a wall of text.
I got caught when I considered briefly signing up for the ‘free delivery/returns’ and moved on to the next page, only to discover i had now bought my item (without putting any card details in) and there was no way to cancel it on the webpage.
People who design roll on to expand ad formats that purposely cover a website mast head that as a user clicks the mast head to go home they inadvertadly click the ad. Sneaking and quite smart!

If you think that the above have “one or two nasty tricks” then try using “arcor” internet access in Germany. It is so full of nasty tricks it is hard to believe. Just some very brief examples such as limiting the number of mails you can view on one page, so that you are confronted with the adverts (when they can find advertisers – for many months no one has ads so the page is always half blank), several times just to view your mail. When you want to click on something – the area clickable is so small that you have to fiddle around with the mouse and it is sometimes not even beside the area, but to one side. If you set more than 10 mails (default) it can display up to 100 mails but regularly (every ten minutes?) it goes back to 10. You have to log in several times in one session, and they call it “log in” and then “central log in” and so you have to type your details twice and many Germans are wary of this and so don’t use it because someone may be “spying on them” so when not using the email system, that leaves more bandwidth for the others who suffer the system. To put a name in the address book is only possible if that person writes you a mail and you hit that “save address button” before replying. This is however a weary myriad of forms to fill in with questions as to “which group does this person belong to?” and then you have to create groups to advance. To remove a name……is impossible – you cannot remove names and thus end up with maybe 5 entries for the same name. They only display just a few names at a time so you have to wade through the “a” entries, then the “b” entries and slowly through to where the “k” for example is, to find that nothing has been stored. They provide a “webspace” but this is also so convoluted to access that no one I know has been able to put anything there. They often “close the service” for repairs at weekends and do anything to make it so useless that I only use it when forced to. When they send you a bill then they quote prices in tiny “6” size fonts for the Euros not with just cents but also hundreths of cents (which do not exist) but they insist that this is more accurate. It also makes the whole page complicated and difficult to decipher. If you make any changes to your account then the period that you are fixed with them is extended by a further two years! To finally cancel the whole thing you have to write to them before the end of the contract just 3 months in advance. Anyone will ask why on earth should one stay with them and the answer is that ALL German internet services are the same. They have a cartel because they all pay huge liscense fees to the German government, thus stick together and no one undercuts the other either in price nor service offered. Portugal is the same and in France too. People there accept that with prepaid cards the additional amount remains on the account for just ONE MONTH and is then “lost”!
But the masses continue to just shake their heads and accept all this nasty annoying ripp-off trickery.
I suggest someone makes a site where these companies are named, their offence listed and then a table of “nasty companies who we don’t want to deal with” is compiled. I WANT to read about which company is the biggest ripp-off above all others and then know not to even think about using their “service”.
Go ahead, be a step ahead for once in your tiny life and do something exceptionally GOOD.
