A recent study into relationships has some bad news for couples. According to a study from ScienceDirect, we've been inflating our partners intelligence.
"People can estimate their own and their romantic partner's intelligence (IQ) with some level of accuracy." the study said.
"However, the degree to which people may overestimate their own (IQ), as well as overestimate their romantic partner's IQ, is less well established."
The results of their study showed that both male and females overinflated their partners intelligence by up to 7 IQ points. However, they found no link between IQ difference and relationship satisfaction.
The study didn't give any indicators as to why we assume our partners are smarter than they actually are.
