people are irrational 90 percent of the time but don’t know it. We can be rational in trivial situations—such as deciding what time to leave the house to drive to work. But we are almost never rational when it comes to matters of love, family, pets, politics, ego, entertainment, and almost anything else that matters to us emotionally. When our feelings turn on, our sense of reason shuts off. The freaky part is that we don’t recognize when it is happening to us. We think we are reasonable and rational most of the time.
A person believes he is rational 90% of the time, and irrational 10%. The truth is the opposite and he does not realize it. Any time feelings, emotions, ego etc is involved AT ALL, we are irrational.
