"Some professionals recognised talk of colours from the infamous Myers-Briggs test, administered by less-respectable management consultants. It built on the mystical ideas of the Swiss psychoanalyst Carl Jung, active at the start of the 20th century, whose theories are now mostly of historical interest. The theory of Myers-Briggs was not something modern psychologists took seriously. Since the test had been developed quite some time ago it had been the subject of extensive research and the results had revealed serious flaws."

The Myers-Briggs corporate product is an interesting confirmation of 20th Century scientific method. With standard methodologies, reviewed and published by standard peer review processes, Myers-Briggs was shown to be useless before 1990. So science seems to work well. Nonetheless, the last time a company I worked for paid (and spent on employee time) for Myers-Briggs testing was 2017. Science works well, but corporate purchasing of consulting does not have such a good track record.
