If you have a hard time choosing paint colors, or which ice cream shop's 31 flavors to buy, this is for you. According to the journal Science, our brains aren't equipped to consider more than 2 options at once. Here's why: The risks and rewards of every decision are mulled over by the rational part of your brain called the medial prefrontal cortex. If you only have 2 choices, one-half of your processing power evaluates option A, and the other half considers option B. But what happens if a third possibility's added to the equation? According to neuroscientists, you end up playing the mental equivalent of musical chairs. First, you compare A and B. Then B and C. And then you compare C and A. And the more options you add, the more one-on-one comparisons there have to be. That's why tasks with infinite options - like choosing paint colors - seem impossible. Because if you're faced with hundreds of choices, you end up flip-flopping between them. What's the fix? Force yourself to work with groups of 2 - for example, red paint or green paint. Once you've narrowed that down, split your available shades into further groups of 2, and keep eliminating one choice until you reach a decision.
