For two hundred thousand years we have had a spoken culture.
And it is only very, very recently we have had a literate culture. And that only in privileged parts of the world.
Spoken culture gives rise to intuitive thinking. While literate culture gives rise to counter-intuitive thinking.
A good example of intuitive thinking is astrology. While a good example of counter-intuitive thinking is astronomy.
Intuitive thinking also gives rise to many false positives. Such as one can intuitively see many false positive correlations in astrology. That is, astrology seems to work - as far as the intuitive mind can see.
And fortunately false positives do not threaten our fitness to pass on our genes. For instance the false positive, "That is a sabre-tooth tiger", is not life threatening. While the false negative, "that is not a sabre-tooth tiger", when it is, will soon have have you on the menu for lunch.
So false positives are not life threatening, while false negatives are life threatening.
And that is why we have been able to survive for two hundred thousand years with intuitive thinking and all the false positives generated by intuitive thinking.
So intuitive thinking has served us well for two hundred thousand years - it has enabled us to survive. Just look how long astrology has been around.
But then the printing press was invented which gave rise to the dream of universal literacy. And this dream has quite recently been realised in the West - look, I am writing this and you are reading this now - we are both literate.
And remember that literacy gave rise to counter-intuitive thinking. For instance the intuitive could see that the sun went round the earth, while the counter-intuitive know the earth goes round the sun.
And indeed almost all of modern science is counter-intuitive.
Another example of counter-intuitive thinking is modern economics. For while the intuitive believed that private avarice led to public destitution - indeed they called it usury, the counter-intuitive know, thanks to Adam Smith, that private greed leads to public prosperity.
And modern liberal democracy is entirely counter-intuitive. For it is intuitive for politicians to seek to continue to increase their power, while liberal democracy, quite counter-intuitively, limits power. See your Constitution and mine.
So while counter-intuitive thinking has given us science, prosperity and freedom, intuitive thinking has given us astrology and MBTI.
Intuitive thinking gives rise to many false positives. This is borne out here where most members give testimony to many false positive correlations between personality characteristics and types.
In other words, to the intuitive mind MBTI seems to work because it continues to produce false positives.
But to the counter-intuitive mind, MBTI is the natural result of intuitive thinking which is validated by ongoing false positives.
In other words, MBTI is self validating.
