I think part of the problem is that especially with decisions of the heart, people make short sighted choices. For example, people who marry young (sub 20) should realize they probably don't have enough information to make that choice. They may not regret their decision later (cognitive dissonance) but they probably could have better optimized. If this doesn't convince you, at least consider the fact that doing this exercise will allow you to be more sure of your "gut" decision should they align and be a tad more wary of it should they disagree.
