Birds of a Feather Do Flock Together. - PubMed - NCBIWe argue that the lack of evidence for personality similarity stems from the tendency of individuals to make personality judgments relative to a salient comparison group, rather than in absolute terms (i.e., the reference-group effect), when responding to the self-report and peer-report questionnaires commonly used in personality research. We employed two behavior-based personality measures to circumvent the reference-group effect. The results based on large samples provide evidence for personality similarity between romantic partners ( n = 1,101; rs = .20-.47) and between friends ( n = 46,483; rs = .12-.31). We discuss the practical and methodological implications of the findings.
Provocative New Insights From the Largest Consumer Sleep Study Ever Released | The Huffington Post• Exercise is good for sleep: Any amount is helpful, but the optimal amount is 30 minutes, which correlates to 14 minutes of extra sleep per night. • Caffeine: Good news here! Three or fewer cups of coffee didn’t notably affect average sleep time much, but those who drank four cups or more slept 26 minutes less. • Alcohol: Surprisingly, those who had one or two drinks slept an average of 16 minutes more than people who had more than two drinks (or none at all).
Using data culled from their most recent 10-K reports, we looked at how efficiently some of the biggest media, entertainment and technologies companies are run as a measure of profitability per employee. To get the figure, we simply divided the fiscal year 2013 net income a company reported in its 10-K (companies end their financial years at different times, some in June, some in September, some in December) by the number of employees it reported. The results were surprising even to us.
