:( not fully validated - evidence supporting increased self disclosure and satisfaction is correlational
may be the other way around - satisfied couples are more likely to disclose information to each other +
could be a third factor to being more satisfied and perceive that each patterned share more information eg/ around of time together
:( lack generalisability - tang et al found that men and women in US shared more thoughts and feelings than people in china. prediction was there would be satisfied couples in USA but satisfaction was the same in both cultures
SO theories of attraction area based on the values of western, individualistic cultures + have poor population validity
