Three parts, five minutes
Every issue has the same shape, so you always know what you’re opening.
One idea, explained properly
A single bias, heuristic, or design pattern — what it is, when it fires, and why it changes what people do. No jargon left unexplained.
The evidence, not the anecdote
What the research actually found, how big the effect was, and where it has failed to hold up. If we can’t measure it, we don’t claim it.
One thing to try
A concrete move for your own work — a default to change, a question to reframe, a step of friction to remove — and how to tell whether it worked.
Defaults do the deciding. Whatever happens when someone does nothing is what happens most of the time.
Where the effect is large, where it shrinks, and what the studies get asked to prove that they can’t.
Find the one default in your product or process that nobody chose on purpose. Then choose it on purpose.
For people who design choices
If part of your job is deciding how a decision gets presented to someone else, this is written for you.
