Why the Myers-Briggs test is meaningless
I have done the real Myers-Briggs process a few times.  It takes a day for a small team, and includes several interviews, the test, and meetings.  The test on its own is pretty pseudoscientific (and gameable), but if you know someone well you can usually guess their MBTI type without a test.  However, the whole process is not a bad medium for introspecting on whether your process works for the individuals on the team, using the &quot;scientific personality profiles&quot; you just developed to talk about your style.<p>For example, one team I was on adopted a meeting agenda before our weekly meetings (the Amazon &quot;6-pager&quot; idea), ostensibly because of the prevalence of IxxJ personality types on the team, and it helped several people become more open.<p>As I understand it, there are now better personality inventories and processes for this, but Myers-Briggs was the OG.
