Exploring the neural substrates of choice and certainty

University of Washington (UW) researchers who study how the brain makes decisions are uncovering the biological mechanisms behind the belief that a choice is likely to be correct.

“Choice certainty,” noted one of the researchers, Dr. Roozbeh Kiani, “allows us to translate our convictions into suitable actions.” Several other research projects have shown that choice certainty is closely associated with reaction time and with decision accuracy.
