If you are reading popular books on social science (which many business books are), it is very likely that the author is pushing research they are personally invested in succeeding. They are often not trying to convey a nuanced understanding of a phenomenon. Furthermore, popular books are often not peer-reviewed to the same extant or at all as regular research literature.

A better alternative is to read review articles in journals. They are shorter than books and will also give a more reasonable estimate of the certainty experts have in a certain field of results. For example, in psychology there is the Annual Review of Psychology, which generally publishes ~50pg readable summaries of literature by experts in the field. For the love of social science, please stop reading popular books on the brain/mind.
