“A … or B? One … or two?”

An eye exam gives us real-time choices between two options.

We’re quite comfortable making the choice when it’s clear. We don’t choose the worse option. We go with what’s better.

But we’re not as skillful when it comes to slower assessments.

Consider comparing two months with any of these criteria:

• One with caffeine. One without.

• One with social media. One without.

• One with adequate sleep. One without.

• One with vitamin supplements. One without.

• One with daily exercise. One without.

• One with a mediation practice. One without.

Are we patient enough to test? Are we sensible enough — upon learning which is better — to choose the better option?

There’s one way to find out.
