This question is about a perception in general and not related to a specific perception.
Suppose an individual has a perception (say X) on a particular phenomenon and later, the individual came to know that her perception is wrong and found the correct perception (say Y) on that phenomenon.
How much time, in general, it takes for the individual to get stabilisation in the new perception?
Or does the transition strongly depends on the individual, environment and phenomenon under consideration so that it is impossible to find the average estimate?
