You probably know that designing for accessibility benefits everyone, but you’re probably thinking of physical disabilities.

But it can hold even more true for cognitive disabilities! UIs with low demands for sustained attention may help ADHD folks more, but it they are less taxing for everyone.

Thanks! Which part of TLDR? Couldn’t see it on their website sadly.

We believe healthcare is a right for every American.

But starting today, millions of people will be notified that they are being priced out of their insurance thanks to Republican policies.

Enough is enough. The GOP may shut down the government, but we will stand tall for YOU.

I have rewritten this post at least 10 times in the past year, so I’m almost in disbelief that I finally managed to hit Publish. 🫣

Hope it resonates!

🔥 New blog post!

Covering, among other things:

- Why making simple things easy and complex things possible is not enough
- How to maximize your UI’s signal-to-noise ratio
- Why you can’t uncover friction through user feedback
- How to prioritize user needs

In the economy of user effort, be a bargain, not a scam • Lea Verou
User effort is a currency. To create a product users love, design the tradeoffs of use case complexity to user effort with the same care you design your pricing scheme.

Neurodivergent conditions are only disabilities because we live in a world not designed for us. Easy to imagine a flipped narrative in a world run by neurodivergents,eg “Patient insists others decode hidden meanings behind their words and compulsively makes eye contact for excessive amounts of time“

AuDHD (Autism + ADHD together) in particular bring a host of superpowers when it comes to entrepreneurship & innovation, and many of the greats are speculated to have been AuDHD by today’s diagnostic criteria: Leonardo da Vinci, Newton, Einstein, Tesla to name a few.

Second, neurodivergence is simply a different way that some brains are wired, and comes with strengths and weaknesses. Many (most?) great innovations of our time came from brilliant neurodivergents who happened to hyperfocus on the right thing.

First, neurodivergent conditions have a very strong genetic component and are highly hereditary. It’s just as unlikely a medication could give you autism as it would be to give you green eyes.

The recent commotion around Tylenol and autism reminded me how many neurotypicals are so uninformed about neurodivergence they think neurodivergent conditions (autism, ADHD, OCD etc) are some sort of plague that you can catch if you’re not careful enough.

Don't get me wrong, I love good marketing. But this squarely crosses the line into deception and #darkpatterns and is not ok.

@virtualaegean.bsky.social please don't be the reason we can't have nice things.

And it gets worse…

Suppose you’re taking a friend along on the trip, so you’re now 3 adults + 1 kid. Then with Family, you actually pay more!

And no, you cannot opt-out of it and book everyone on a regular Flex fare. Chances are, you likely wouldn't even know, and would be glad for the "discount"!
lea.verou.me
That wipes out even that 5%, making the grand total of savings less than $1, an effective discount of 0%.

In fact, after I took these screenshots, the fare changed slightly so in the OP screenshots the difference is literally $0.00!

Surely, 0% is as bad as it gets, right? Wrong. [5/7]
lea.verou.me
Worse, for the more common 2 adults + 1 child the "40% off" is an even more meager 5.66%:
$319.88 * 3 = $959.64
$362.13 * 2.6 = $941.538
3 - 941.538 / 319.88 = 5.66%

Actually, it's not even that.

Remember the weird mysterious alchemy involved in the actual total when you use the Family fare? [4/7]
lea.verou.me
…But wait, why is the total higher?

Notice the total at the top right is not actually $579.408, but $595.04, a difference never explained in the UI.

If we do the math based on actual totals, the effective discount is even lower:
2 - 595.04 / 319.88 = 14%

And it gets even worse… [3/7]
lea.verou.me
Exhibit A: ATH-VIE on Sep 30
2 adults: Flex is $319.88/pax
1 adult + 1 kid: Flex → Family, now $362/pax (+13%). Flex no longer bookable.

So how much is the actual discount?
$319.88 * 2 = $639.76
$362.13 * 1.6 = $579.408
2 - 579.408 / 319.88 = 18.9% off

But it’s actually even worse… [2/7]

I like Aegean Airlines but their "40% discount for children" is a scam.

tl;dr: The "40% off" is based on a fake inflated fare. The effective discount is 14% for 1 adult + 1 child, 0% for 2 adults + 1 child, and actually increases for adult:children ratios > 2:1 with no opt-out.

These are web developer complaints related to interop (e.g. lack of browser support, features working or looking different across browsers etc)
lea.verou.me
Computing some preliminary analysis over the #StateOfHTML pain points data and some …interesting patterns are emerging 🙃
Two Pie charts titled "Complaints about specific browsers" showing about half Safari browser, around a third Firefox, and about a sixth Chrome Two Pie charts titled "Complaints about specific vendors", one titled "All complaints" and the second "Explicitly about interop". The first is showing around 55% Apple, with a tiny sliver of Microsoft and the rest split evenly across Google and Mozilla, whereas the second is 100% Apple. Two Pie charts titled "Mobile vs desktop", one titled "All complaints" and the second "Explicitly about interop". Both are showing about a third desktop and two thirds mobile. Two Pie charts titled "Complaints about specific platforms", one titled "All complaints" and the second "Explicitly about interop". The first is showing around three quarters iOS, around 15% Android, a tiny sliver of Linux, and the rest split evenly across MacOS and Microsoft Windows. The second chart is >80% iOS, with the rest being Android.

mekka makes the hard financial case for free universal child care

surprise! like every social program, it’s profitable for society and not just because it’s “nice”

Ha! Capitalism and taxing the poor wins again! Check out my infinite money hack!

* Median childcare salary in NYC is ~$40K

* Median salary overall in NYC is ~$80K

* Infant childcare has a "1 adult to 2 infants" ratio.

* So for $40K of free childcare, I can send 2 primary caregivers back to work!

So, if trans people committed mass shootings as often as cis people, you'd expect to have had about 52 of them since 2015. But instead, 5.

Trans people are literally 10 times safer than cis people.
