Prenatal Testosterone Exposure (2D:4D) and Economic Preferences

Short Description: Second-to-fourth digit ratio (2D:4D) of human hands, a putative marker of prenatal testosterone exposure, has been argued to be one potential explanation for heterogeneity in economic preferences. In a pre-registered study based on a much larger sample than in previous studies, we test if 2D:4D is associated with economic preferences (risk taking, altruism, negative reciprocity, positive reciprocity and trust).

Methodological Details: Hand measurements were done with digital calipers. For economic preferences elicitation, a part of the global preferences module of Falk et al. (2018) was used. These eight items are experimentally validated.

Risk:

“How do you rate yourself personally? In general, are you someone who is ready to take risks or do you try to avoid risks?”

Altruism:

  1. “Imagine the following situation: Today you unexpectedly received 1,000 Euro. How much of this amount would you donate to a good cause? [0,1000]”

  2. “How willing are you to give to good causes without expecting anything in return?

(scale from 0-10)”

Positive Reciprocity: “When someone does me a favor I am willing to return it.” (scale from 0-10)

Negative Reciprocity:

  1. If I am treated very unjustly, I will take revenge at the first occasion, even if there is a cost to do so. (scale from 0-10)

  2. How willing are you to punish someone who treats you unfairly, even if there may be costs for you? (scale from 0-10)

  3. How willing are you to punish someone who treats others unfairly, even if there may be costs for you? (scale from 0-10)

Interpersonal Trust: People are basically honest (scale from 0-10)
