An emerging adult who makes significant gains in postformal thinking is more likely to operate from the core belief that her beliefs are:

not absolute truths, but rather one way of seeing the world.

Explanation:

Postformal thought is term that describes the tendency of individuals to be analytical, more flexible, and readily open to accept moral and intellectual intricacies, and rationalistic than previous stages in development.

Thus, postformal thinking is considered to be more realistic on the basis that, very few positions, ideas, situations, or people are completely right or wrong.

For example, people who were considered angels or devils by the neighbors later shown to be just people with strengths and weaknesses, endearing qualities, and faults to those not in the neighborhood.

Hence, an emerging adult who makes significant gains in postformal thinking is more likely to operate from the core belief that her beliefs are: "not absolute truths, but rather one way of seeing the world."
