I have worked at many organizations that make key leadership decisions based on personality assessments, like Myers Briggs and Predictive Index. Always seems more counter-productive than effective for many reasons. Not the least of which that personality is dynamic not static; contextual factors significantly influence emergence or suppression of personality traits. For example, a natural introvert may be emboldened in certain social situations with certain people. 

In addition to not effectively considering situational factors, personality assessments fail to properly consider individual choice and self management. For example, in attempting to determine the personality characteristics for coping in remote and harsh environments like arctic winterovers, research generally shows that personal choice, volunteering, usually trumps personality characteristics. 

Also important to consider is the Foyer Effect, also know as the Barnum Effect. The Foyer Effect is the tendency of people to believe general statements--like those in horoscopes--describe them, as long as the statements are favorable. For example, whenever I use Myers Briggs, DiSC or any other personality assessment in a class I ask the students to tell me to what degree they think the results correctly describe them. I invite the true believers--100%, it nailed me, it perfectly identified my personality--to share their style with us. The true believes are usually eager to share. I then say, "so, according to that style you are..." I then read characteristics from all personality classifications than the one they received in their test results. Almost always--actually, never seen it happen differently--the student will say something like "absolutely, that's me". I then divulge that I read excerpts from every other personality type but the one the test identified. I then explain the Foyer Effect and encourage them to critically assess the assessments. 

I dont' say this to debunk the assessments; I say it to encourage professionals and students to consider OTHER factors--do not make decisions about a person based entirely on a personality assessment that, at best, is a snapshot of a moment in a dynamic phenomena. These types of assessments are ideal for self reflection and team development. 

For example, consider conducting a team exercise like the following:

In short, avoid categorizing and judging people based on personality assessments alone. Consider limiting the personality assessments as opportunities for self reflection and team development.

Regards,

Brent

One of my colleagues Elisabeth Brauner, an organizational psychologist, had this comment on the original post which I forwarded to her:

"The team/group research folks are divided about the importance of personality because often team dynamics override personality differences. I would also be careful to use this as a recommendation because teams in real life are seldom composed based on the compatibility of their personalities."

>>> I've been thinking a lot about "personality types" lately, and how they might relate to team performance. I would guess that teams with a mixture of different personality types might perform better than those whose students all have the same personality type, and I would also think that it would be good experience for students to have to work with people that have different personality types from their own, independent of whether exposure to different types serves to increase performance.

>>> I am curious to know if any of you use personality type (e.g. Myers-Briggs) information to help form teams, and if so, whether you think it's worth the effort. Do you form the teams on the first day of class? When do you ask the students to complete a personality type questionnaire? Do you try to make sure that the personality types are evenly-distributed across the teams, or do you use some other kind of distribution strategy?
