How do people think and make a desicion?

Answer 1

Thinking, or cognition, is generally achieved by the connections and carrying of signals via brain cells (neurons). This cognition is developed via perception, the senses, knowledge and learning, and many other factors.

Making a decision involves many of these factors, but also involves what resources are available to us, the presence of stress or emergency, the way we are socialized/cultural norms, etc. The best time to make a decision is when we are calm, have as much information as possible, have the opportunity to consult an expert or trusted other, and when we have plenty of time to think it over. The reason for this is that stress can inhibit our ability to think clearly and rationally, and diving into a situation or commitment while uninformed can be dangerous. Unfortunately, this ideal situation is not always possible. Typically, a person makes a decision by weighing their options and consulting trusted others. This is good practice, but with big decisions it is ideal to strive for the situation mentioned above.
