We broke Weber's law. By manipulating the prior (ie the frequencies of small and large magnitudes), we changed how people's accuracy depended on magnitude. When large magnitudes were more frequent, subjects became more precise about them. This points to efficient coding, dynamically implemented.

A welcome opportunity to revive this one
Meme-style slide with a light blue gradient background, titled 'STOP CALCULATING INDEX VARIABLES' in large bold black letters at the top.

Below the title, a bulleted list in black text:

NUMBERS WERE NOT SUPPOSED TO BE MASHED LIKE THAT
YEARS OF RATIO VARIABLES yet NO CONTROL FOR THE DENOMINATOR achieved
Wanted to account for the denominator for a laugh? We had a tool for that: It was called "CONTROL VARIABLE"
"Yes please give me ONE kilogram times years per square meter of something" – Statements dreamed up by the utterly Deranged

Below the bullets, unbulleted text reads: 'LOOK at what researchers have been demanding your Respect for all this time, with all the computers we built for them' followed by a bolded line: '(These are REAL Index Variables, done by REAL researchers)'

The bottom portion shows several mathematical formulas with red question marks scattered beneath them, implying mock outrage/confusion:

A formula for Simpson's Diversity Index: D = 1 − (Σn(n−1) / N(N−1)), followed by red '?????'
A small formula labeled CD = (#○−#□)/(#○+#□+#▲) = 1/6, next to a diagram of shapes (triangle, diamonds, squares, circles) connected by arrows radiating from a central dark diamond, followed by red '??????????????'
The Euclidean distance formula: d(p,q) = √((p₁−q₁)² + (p₂−q₂)² + ... + (pₙ−qₙ)²), followed by a long row of red question marks

At the very bottom, the phrase '"Hello I would like 🔺 apples please"' appears (with a small colorful 3D geometric/fractal icon in place of a number), followed by the closing line in bold black text: 'They have played us for absolute fools.'
