Thank you both for writing! Very interesting. Great team :)
the association between money and happiness was strongly moderated by individuals’ answers to “How important is money to you?” This raises an interesting question about causality: do people value money because they know it makes them happier, or does it make them happier because they value it?
I would like to know more about the differences in the happiness between the groups who answer that “How important is money to you?” question differently. Is there anything out there that I should look at? With the data you have, can you for example, plot a graph showing how the happiness of bottom quartile of money valuers (i.e., those attaching very low value to money) scales with income and compare it to the top quartile?
