Age-at-death forecasting – A new test predicts when a person will die. It’s currently accurate within a few years and is getting more accurate. What psychological impacts might knowing your approximate (± 6 months) death time mean for otherwise healthy people? Does existing research with terminally ill or very old persons shed light on this? What would the social and political implications be? What if a ‘death-clock’ reading became required for certain jobs (elected positions, astronauts, roles requiring expensive training and education, etc.) or decisions (whom to marry or parent children with, whether to adopt, whether to relocate, how to invest and manage one’s finances, etc.)?
“The findings revealed that neural response similarity was strongest among friends, and this pattern appeared to manifest across brain regions involved in emotional responding, directing one’s attention and high-level reasoning. Even when the researchers controlled for variables, including left-handed- or right-handedness, age, gender, ethnicity, and nationality, the similarity in neural activity among friends was still evident. The team also found that fMRI response similarities could be used to predict not only if a pair were friends but also the social distance between the two.”
