The University of New Mexico says a psychology professor's tweet that people battling obesity don't have the willpower to finish doctorate degrees wasn't part of any research project as he claimed.
KOB-TV reports the school's institutional review board found that Geoffrey Miller's tweet was instead "self-promotional."
Miller wrote on Twitter last month that obese doctoral applicants who don't "have the will power to stop eating carbs" won't "have the willpower to do a dissertation." The tweet has since been deleted and his Twitter account has been made private.
He later apologized and said the tweet was part of a research project.
Miller is on leave from UNM while serving as a visiting professor at New York University.
UNM officials say the school is conducting a disciplinary investigation.
