MBTI is a bogus personality test foisted by the military on those under their command, I repeat, under their command, during and since WW II.
And MBTI is a bogus personality test foisted by business on their employees, I repeat, on their employees, for about the same period of time.
And MBTI is a bogus personality test foisted on school children by the middle aged.
In each case those with power are foisting a bogus personality test on those without power, and in the case of the military, on those under their command.
But those in power have a duty of care to the vulnerable. But rather than exercising their duty of care they use their power to take advantage of the vulnerable.
This is called the abuse of power.
