Likeability ratings provide reliable estimates of [[subjective value]] [[Lopez-Persem 2020 Four core properties of the human brain valuation system|(Lopez-Persem et al., 2020)]]; they also predict behavioral measures such as choice, reaction time (RT), and confidence. Early studies relate neural activity to objective measures (e.g., reward magnitude, probability, delay), even though choice preferences are subjective. However, there are [[problems with the concepts of utility and value]]. # References - [[Kable 2007 neural correlates of subjective value during intertemporal choice]] - [[Hayden the case against economic values in the brain]]
