Accurate personality judgements are essential in social living and many other fields. When talking about personality, we are referring to characteristics or traits that are quite stable and vary between individuals.<\/p>\n

In personnel selection, personality traits are important predictors for aptitude: sales representatives should be high on extraversion, while accountants should possess an acceptable level of conscientiousness.<\/p>\n
A recent study<\/a><\/strong> found that computer judgements based on Facebook \u2018likes\u2019 were more accurate than personality judgements made by colleagues, friends and even spouses. What does this mean for the future of talent assessment and analytics?<\/p>\n Individuals are reasonably good at judging the personality of others. This is also true for strangers, as well as for judgements based only on short video sequences. The usage of online profile data to generate predictions about traits or preferences of individuals is rather new. There are also some \u2018special\u2019 studies, for example, one that found that people who listen to (or at least like) Beethoven are more intelligent than those who listen to Beyonc\u00e9. <\/a><\/strong> This study applied some very questionable methods, but many more serious approaches are based on the same principle. You like something on Facebook; a computer tells you who you are.<\/b><\/p>\n Three researchers from the University of Cambridge, UK, and Stanford University, USA, compared the accuracy of computer-based personality judgements to those made by humans. The computer won.<\/a><\/strong> As for any study, there are some limitations in regard to the one presented here. Nevertheless, the crucial question is, if the same principle works also for talent analytic approaches, do computer-based models make more accurate judgements than those made by recruiters and hiring managers? For Facebook, this approach is limited by the fact that some data needed for such models is not public, due to privacy settings. However, business networks such as LinkedIn have some comparable features.<\/p>\nWhat can someone\u2019s \u2018digital footprint\u2019 tell us about them? <\/span><\/h5>\n
A computer needs 250 \u2018likes\u2019 to judge better than your spouse <\/span><\/h5>\n
\nAs sample, data of more than 10,000 volunteers from the myPersonality<\/strong> <\/a> were used. In this project, Facebook users were offered an app to complete evaluated personality questionnaires and receive feedback on the results. In addition, some of these volunteers also rated co-workers, friends, family members, and other Facebook friends on personality scales. The correlation between those self-ratings and other ratings were compared with the regression model that estimates a personality profile based on the Facebook user\u2019s \u2018like\u2019 behaviour. The computer-based model needed only ten \u2018likes\u2019 to outperform the accuracy of co-workers\u2019 ratings and 250 \u2018likes\u2019 to outperform the rating of spouses.<\/p>\nDoes the same principle work for talent analytics? <\/span><\/h5>\n
