    In a new Cognition paper, Barbara Pavlek, & I try to "reverse-engineer" cash. The design of coins is adapted to our cognitive biases. Knowing them, we can uncover hidden patterns in coined currencies. Thread (1/10).

    What do cultural evolutionists mean by 'evolution'? Do we mean the same? Find out in this survey and win the latest books on cultural evolution.

    So most coins are fine pieces of engineering. But what about that Lincoln penny study? Well, the subjects were actually quite good at remembering the features that set the penny apart from other coins. They forgot what was irrelevant. (10/10)

    We also show that coin sizes track coin values logarithmically. Reasons to expect this come independently from economics (marginal utility theory) & psychology (the view that our minds represent magnitudes with log functions, applied to money by dehaene handle).(9/10)

    We show that coin designs are more likely to differ between coins that differ more in value. Value differentials are bigger for coins with different designs or colours. This keeps the cost of mistaking one coin for another low, yet keeps the currency visually simple. (8/10)

    What does that mean for coins? We predicted that coin designs & colours should mark out the differences between coins that matter. In all currencies, high denominations are spaced farther apart (compare 1–2 cents vs. 25–50 cents). Confusing them is more costly. (7/10)

    A simple system has few categories: it is easy to remember & use. An informative system has more categories & is more precise. Languages manage to solve this tradeoff by having more categories for important things (close kin; warm colours), fewer categories for the rest. (6/10)

    Cognitive linguists show that our categories obey an "informativeness-simplicity trade-off". When we name colours, or kinship ties, there are things we tend to lump together (older & younger sisters), while we distinguish others (fathers & mothers). (5/10)

    We show 2 things about today's coins. (1) coin designs are more distinctive for higher-value coins; (2) coin sizes track coin values logarithmically. These two features were derived from cognitive mechanisms. (4/10)

    If true, that's a problem. The mistakes we make when counting coins are expensive. The way cash appears to us also has economic consequences: our perceptions of value are influenced by the size or aspect of coins & bills (even if it's not relevant). Psychology matters. (3/10)

    Coins should represent quantities of money in a memorable, easy-to-process format. Are they up to the task? Previous research said: not really. People can't pick the USD penny among different pictures (left), can't draw it from memory (right). (2/10)

    I am not sure if the WEIRD acronym was intended to be a falsifiable prediction, but this is for me a very surprising lack of variation across the world. A few more of these, and we might want to leave the N = 70.000 studies for theories where we expect something will happen?

    So it looks like "loss aversion" is not a real thing. This affects a lot of my previous design, not to mention strategies for life:
