An Empirical Assessment of the Cost of Dichotomization of the Outcome of Clinical Trials https://onlinelibrary.wiley.com/doi/10.1002/sim.70402
"Burdening more participants than necessary is wasteful, costly, and unethical.
… trials with a binary outcome have larger sample sizes on average, but also larger standard errors and fewer statistically significant results. We conclude that researchers tend to increase the sample size to compensate for the low information content of #binary outcomes, but not sufficiently.
… estimate that on average, only about 60% of the information is retained after #dichotomization
… hope that quantifying the loss of information will discourage researchers from dichotomizing continuous outcomes"

Here is a “magic trick”
Give kids colored cards.
red card- 1 dot
blue card- 2 dots
green card- 4 dots
yellow card- 8 dots
“Show me a total of x dots!”
(x is a number between 1 and 15)
“look around, why are you all holding up the same cards? isn’t anyone creative enough to find another way?”
then ask what goes on the “next card” #matheducation #math #binary

I've been to #Italy and had conversations with cool #Damanhur friends about this, can confirm it's actually true. Italian and Greek remain the two most #binary #languages I'm aware of. Don't get me started on how that impacts #culture- those tropes exist for a reason 😜
