Many studies focus on how we prioritize and make decisions. One of the most important contributions to this field has been the advent of neuroscience research over the past few decades. Until recently, we have not been able to map and watch how the brain activates throughout a decision-making process. Now we can.

A notable experiment in 2000 was the Jam study, where researchers found that more people bought jam when there were fewer options. Decision-making requires willpower. As the days goes on the more decisions we make the more this resource is drained, which can lead to easier or even unhealthy choices.

Basically, the study concluded that if we remove the temptations to divert energy toward decisions that are less important, your most important decisions get the most-resourced version of you possible throughout the day.
