How Conspicuous Consumption Helps Men Get Laid
That girl you know who says she doesn't care about money? She's STILL going to say "Wow!" when she sees it, and she's not going to say "no" when the guy tells her to get in.
THE SCIENCE ON CONSPICUOUS CONSUMPTION
First off, here's how increased mating options affect both men's and women's public displays, from 2007's "Blatant benevolence and conspicuous consumption: When romantic motives elicit strategic costly signals", published in the Journal of Personality and Social Psychology:
“Conspicuous displays of consumption and benevolence might serve as "costly signals" of desirable mate qualities. If so, they should vary strategically with manipulations of mating-related motives. The authors examined this possibility in 4 experiments. Inducing mating goals in men increased their willingness to spend on conspicuous luxuries but not on basic necessities. In women, mating goals boosted public-but not private--helping. Although mating motivation did not generally inspire helping in men, it did induce more helpfulness in contexts in which they could display heroism or dominance. Conversely, although mating motivation did not lead women to conspicuously consume, it did lead women to spend more publicly on helpful causes. Overall, romantic motives seem to produce highly strategic and sex-specific self-presentations best understood within a costly signaling framework.”
