What Makes a Decision 'Rational' or 'Impulsive'?

A rational decision is one you think about before making. It feels calm and planned, like choosing your favorite ice cream because you know it tastes the best. An impulsive decision happens quickly, almost on instinct, like buying that toy right away even though you didn’t plan for it.

Sometimes, your brain uses different parts when making a choice. When you take time to think, it’s using the part of your brain responsible for reasoning and planning. But if something feels exciting or urgent, your brain might jump in with a quicker, more emotional response.
