Contrary to popular notion, spouses do not become more similar over time, according to a team of researchers led by Michigan State University.

Our goal in conducting this study was to help resolve this debate," said Mikhila Humbad, lead investigator.
The researchers analyzed the data of 1,296 married couples, one of the largest such studies to date, said Humbad, MSU doctoral candidate in clinical psychology. The data came from the Minnesota Center for Twin and Family Research.
The researchers wanted to know if husbands and wives become more similar as the marriage progressed.
They examined a host of personality characteristics and found that, in most cases, the couples did not become more alike with more years of marriage.
The conclusion: Spousal similarity is better explained by selection than gradual convergence. The one exception to this pattern was aggression.
