Group self-investment predicts guilt up to a tipping point where further investment suppresses it

Evidence

The curve was at minimum (i.e. the slope is equivalent to 0) when (z-standardized) self-investment was −0.28. We created two variables (invest_low & invest_high), each centered around −0.28. For invest_low, values above −0.28 were converted to 0. This represented the relationship between self-investment and collective guilt when self-investment was below −0.28. Similarly for invest_high, values below −0.28 were converted to 0. This represented the relationship between self-investment and guilt when self-investment was above −0.28. We then submitted collective guilt to multiple regression analysis including invest_low, invest_high, self-definition and selfdefinition squared. As expected, results showed a positive coefficient for invest_low, unstandardized b = .35, t(299) = 3.13, p = .002, indicating that the relationship between self-investment and collective guilt was positive at low to medium levels of selfinvestment. In contrast, the coefficient of invest_high was negative, unstandardized b = −.31, t(299) = −2.37, p = .018, indicating that the relationship between selfinvestment and guilt was negative at medium to high levels of self-investment. Results of the piecewise regression thus confirm that the curve was an inverted U-shape. — Torsten Masson and Markus Barth, The identification-guilt paradox…, 60

  • QUESTION: The inflection at −0.28 z is below the mean — does that asymmetry mean most people in these samples already sit past the tipping point toward glorification?
  • DEEPTHINKING: The clean b = +.35 below and b = −.31 above the inflection — a near-mirror slope reversal across a single point — is a strikingly sharp discontinuity for such a low threshold.
