Decision costs can be translated as energy we spend on choosing one option over others. That is, more choice is more “costly” for us as decision-makers. What happens is that, when making any kind of choice, our brains begin processing “mini calculations,” like weighing the potential rewards of making a good choice against the cost/ energy of deciding between the options. As the amount of options we have increases, the potential reward of making a good choice increases, but so too does the cost involved in making the decision itself (i.e. more variables to consider, more gains and losses to weigh out, more time spent and more energy used overall).
