Sociosexuality (SOI-R) → Income hypergamy preference
Unrestricted sociosexuality is not a stealth measure of 'women want richer men'.
Observational · Low
The association does not survive the backdoor. Usually SES, outdoor time, or healthy-user bias.
Mechanism
Penke and Asendorpf (2008) gave the field a stable SOI-R. Pop-evo threads collapse that instrument into resource hypergamy or into Buss's youth-preference item. Different constructs, different questions, often opposite short-term vs insurance logics.
Caveats
Correlations between SOI and mate-preference items exist in some samples and are sex-differentiated. They do not identify a causal path from sociosexuality to hypergamy. The stamp is smoke so the collapse has a place to die.
Effect
qualitative. SOI-R measures orientation to uncommitted sex. Hypergamy measures resource weights. They are not substitutes.
