 In a different set of studies, observers watched a silent clip of a man entering an empty room, reading a weather report, and then exiting the room; yet they were highly accurate in assessing his masculinity, extraversion, conscientiousness, and neuroticism levels.Additional research has replicated these results while additionally finding that life satisfaction was perceivable in these thin-slices as well.One set of studies conducted in 2003 asked participants to view silenced clips of one minute or less depicting an individual engaging in an informal social interaction and found that observers were able to accurately assess the IQ of the observed person well above a chance.
