Discussion #19 – “You’re Not My Type” – the Science and Ethics of Personality Testing

We’re joined this week by musician, writer and director Polash Larsen for a critical look at the world of “personality testing” and in particular the famous Myers-Briggs Type Indicator which categorizes people (“personalities”) as four-letter codes (e.g. ENTP).

If you like Myers-Briggs, I should warn you that we don’t (much). As gentlemen scientists, we’re not fond of any scheme that seeks to linearize a complex, non-linear system – especially when that scheme is then used as a guide for how to treat other people.

Calling someone (or yourself) an ENTP is fine as a game, but claiming it’s somehow scientific is wrong. It’s arbitrary and made up. And then using it to pre-judge people – well, that raises ethical questions.

Personality testing and Myers Briggs in particular is very popular in certain circles (e.g. recruiting). The assumption that people have unified “personalities” and that these don’t change over time is common enough to have become a part of our language (she’s not my “type”). There’s something comforting about labelling other people and yourself.

Polash puts forward a plausible hypothesis about this – do we just label ourselves to be who we want to be?

[By the way, the soundtrack for today’s podcast is Paula Abdul’s Opposites Attract. Don’t ask us to explain – just go with us on this one.]

Update Monday 2/11: BTW Paula Abdul sends her love! (no, really)

Horoscopes and fortune telling are fun, but we don’t hire and fire based on them (although, see footnote about Raymond Domenach below). By putting people in boxes, we deny them the opportunity (the right!) to surprise us. Labelling people has a painful history – let’s just be careful.

Special note: we should really issue a (mild) bad language warning for this week 🙂
