Mental Fast Food™ —
things worth thinking about.

A by-product of research at the EQUORA Institute — not the residue, but the usable part. When a number everyone repeats turns out to answer the wrong question, when a chart changes the moment you ask differently, when a decision framework fits on one page: that's Mental Fast Food. Each piece ends not at "now you know" but at what you can actually do.

Swim shirt or sunscreen:
what is each good for?
The sunscreen number comes from health outcomes in people, the shirt number from UV transmission measured in a lab. A slider and body map show which applies where, and what survives the beach.

The qubit count went down,
the machine got better
IBM's 2023 processor had 1,121 qubits, its 2025 one has 120 — the smaller number is the better machine. Eight technologies on five yardsticks, where the ranking flips with the metric.

Why do we like deadlines
more than processes?
A widely shared graphic got two of the EU AI Act's five dates wrong. A switchable timeline and a six-question filter: a date fits in one image, scope takes questions to establish.

weights of evidence
A parenting post cites Siegel, Porges, Neufeld, Kohn and Winnicott as if the same settled science stood behind each. Nine claims on two axes: strength of evidence against firmness of wording.

Why do we eat
these animals?
Beef, pork and chicken are 80% of all meat — not for health or efficiency, but because that is how it was decided between 1945 and 1980. A question-switch on what "less meat" really means.
