Sorry to get off-topic, but this article resonates with this American named Nadav Natan Manham.
Hang on a minute . . . maybe it's not so off-topic. This blog is ultimately about how to evaluate people--the people who are investing your capital. A difficult task, for many reasons. Perhaps the most difficult reason for us to confront is the fact that we the evaluators are so deficient in many ways. All kinds of biases and prejudices we hide from ourselves get in the way of the rational evaluation of others.
One bias is the simple similarity bias. We like people who are like us--who look like us, talk like us, have names likes ours, etc. I'd be willing to bet that if even the most sophisticated money manager selectors (those who spend many millions of dollars of time and effort to evaluate investors strictly on the basis of merit and expected return) were to examine their money managers, they'd find evidence of similarity bias: the same background, same religion, same college attended, same way of speaking, whatever.
If you don't take pains to identify and root out your own similarity bias and other biases, you're setting yourself up to be a sub-optimal people evaluator.
