A mathematical mind works in reverse: a matrix is a special case of a tensor, a vector a special case of a matrix.

In probability, those NonRussians who start from special cases make yuuuge mistakes in higher dimensions (like idiotic psychologists/geneticists w/IQ problems). https://twitter.com/bindureddy/status/1348736075812933632
You can see the problem with:
+ Distributions: economists & statisticians have no consciousness that the Gaussian is a special case & can't handle the more general.
+ "Correlation" is special to linear association & people think it is "evidence based".
+ "Sharpe ratio", factor...
For instance something as basic as correlation (2 dimensional metric) is misinterpreted in the IQ literature & elsewhere. https://www.academia.edu/39797871/Fooled_by_Correlation_Common_Misinterpretations_in_Social_Science_
