They were intellectuals before, but when became "christians" they became dumb. This is the effect of the charismatic movements. And by superficial means, they try to show they are clever, "filled" by the Holy Spirit, but in fact, they merely copy the acts of those who are truly spiritual.
Why don't they change? I would say for one, it's laziness. Laziness to think. To study, to take the hard path. Masking their pride with a spiritual hypocrisy.
