I think you need to get happiness from self reports, asking somehow how good-bad they feel right now.
How do you handle the problem of inconsistent self-reported welfare over time, such as in this example?
And there’s also the standard issue of interpersonal comparisons. For instance, how do you handle a person who would not accept 1 second of torture for any amount of happiness? If that person is tortured, what welfare score does she get? Perhaps she would want to say “negative infinity”, although you could prevent that by setting a lower bound on how negative her self-reported welfare could go. That arbitrary lower bound would then strongly influence the degree of weight given to suffering vs. happiness in utilitarian calculations.
WTA determined like this per species averaged over many individuals with transparency about the variance of the samples seems at least better to me than our current state of knowledge.
Definitely. :) More such studies should be done. That said, they don’t resolve the fundamental issues of interpersonal comparisons and intrapersonal comparisons over time.
Cool. :)
