In fact, correct logic and thinking are much more important than hard skills such as data analysis. Take the logical relationship between famous schools and excellent people that I explained two weeks ago as an example. The main reason why they are talented is not because of the education of famous schools, but because they are born excellent. If data analysts do not have correct logic and thinking, according to data analysis, the formation of talents is mainly due to the education of famous schools. This will form self-bias. This will cause a series of decision-making deviations in the future.
