administration of Oxytocin (OT) increases the transfers made by investors in
the trust game – suggesting that OT increases trust in strangers. While
subsequent studies investigating the role of OT in the trust game found
inconclusive effects on the trusting behavior of investors, they deviated from
the Kosfeld et al. study in an important way as they did not implement a
minimal social contact between the investors and the trustees in the trust
game. Here, we will carry out a large double blind and placebo controlled
replication study of the effects of OT on trusting behavior that implements the
minimal social contact condition and compares it with a no‐ social‐contact condition.
The sample generates a power of more than 95% to detect a true effect of OT on
trusting behavior in the trust game.
