I understand that this article is saying personality tests are similar to horoscopes in that they are not scientifically proven/accepted.

But, there is one huge difference between horoscopes/blood types and personality tests: the former identify people's personality by what they were born with, while the latter attempt to base their results on questions put to the individual of how they think or would act in a certain situation.

There is no room for change in the former. It's fatalistic. The latter always has possibility of a different result. It's based on a person's will.

In that sense, I cannot really think of them as the same at all.

Whether either or both are bullshit or not, I reserve judgement🤪
