Do New Dating Trends Create More Options or Bigger Barriers?

See on Scoop.itBrain Tricks: Belief, Bias, and Blindspots

Two very different interview questions generated the same response.

We’re lonely. We’re disconnected.
Like a dark cloud, loneliness has crept across our ever-buzzing society. Email, cell phones, online dating, Instagram, Twitter and Facebook offer instant social intersection, but little real connection—because we’ve amped up the idea of efficient living far beyond its intended use.

We share our dreams on Pinterest but can’t find time for a heart-to-heart conversation. Instead of creating connective ties, the integration of technology has tied many of us up—bound to multi-tasking behaviors that prevent real connection. Remember how much time we were going to save with smart phones and emails? In the old days, before lunch was an Instagram photo—and we registered “special” with our senses rather than by how many likes it got on Facebook—communication required actual face time. Now, even those very words have been usurped and sandwiched by Apple® into an app that allows us to see faces from afar.

Endogenous Social Identity and Group Choice

See on Scoop.itBounded Rationality and Beyond
Abstract: This paper tests social identity theory with respect to individuals’ self-identification behavior. We report results from a laboratory experiment in which subjects choose their group membership, which is interpreted as decision to identify with the respective group. Inducing a trade-off between monetary payoffs and different group identification choices we elicit the respective implicit valuations of identifying with different groups. The variation of these valuations is in line with the predictions from social identity theory: Subjects have a higher valuation for identifying with groups with a higher status and with groups to which they have a smaller social distance. Finally, we show that this behavior predicts individual out-group discrimination in allocation decisions, which has previously been shown to be associated with social identity. Overall our results provide strong support for the notion that individuals optimize behavior with respect to social identity.
