A simple case study where model error shows the claims in a paper published in a “prestigious” psychology journal to be false. Why worry about low R^2.

Explanations for the last video [Difference Between Clinical and Evidence-Based Knowledge]: Why the statistical properties of a group will NOT particularize to any individual member of the group.
[YouTube] Evidence-Based Science & Mistakes in Particularizing the General (Simplified)
1) The law of large numbers (properties of aggregates) works in one direction. Why you can generalize from particulars, never particularize from generals.
2) The difference between clinical, statistical, and risk management approached. Why they don’t scale.
3) Never compare Mediocristan to Extremistan (Covid to car accidents).

[YouTube] Why Nassim Taleb Thinks Bitcoin is Going to Zero Dollars?
Explained in 4 Minutes
Yedidya Levy briefly discusses some of the reasons Nassim Taleb states that Bitcoin will in fact go to Zero. Nassim recently published a paper titled “Bitcoin, Currencies, and Bubbles.” It is also referred to as #bitcoinblackpaper.

[YouTube] P-Value Hacking
We saw that 1) many metrics are stochastic, 2) what is stochastic can be hacked. This is the simplification of my work showing that “p-values are not p-values”, i.e. highly sample dependent, with a skewed distribution. For instance, for a “true” P value of .11, 53% of observations will show less than .05. This allows for hacking: in a few trials, a researcher can get a fake p-value of .01.
