There is only one definition of heritability used in biology, and it's the one I mean: http://en.wikipedia.org/wiki/Heritability#Definition http://en.wikipedia.

Your implication that it's disingenuous that the layman's definition differs from the scientist's definition... is dumb.
And again, I didn't say that personality was immutable. I said that part of it was. Longitudinal studies show that a correlations of personality across an individual's lifetime is about .83, which is pretty damn high. http://arjournals.annualreviews.org/doi/abs/10.1146/annurev.ps.41.020190.002221 http://arjournals.annualreviews.org/doi/abs/10.1146/annurev....
There are a billion and a half studies on this, and heritability estimates range between 20-45% for different personality traits being tested. http://highered.mcgraw-hill.com/sites/0070366055/student_view0/chapter4/chapter_outline.html http://highered.mcgraw-hill.com/sites/0070366055/student_vie...
- xenophanes 17y agoNo need to call me dumb! Here is an explanation about the word heritability: http://cscs.umich.edu/~crshalizi/weblog/520.html http://cscs.umich.edu/~crshalizi/weblog/520.html Whether a person does change their personality is a different issue than whether it could be changed (possibly requiring some new knowledge, or possibly simply requiring a change in preferences). So that correlation study doesn't provide evidence of immutability. I know there are a lot of studies on heritability. Now, if you are interested in an open discussion, cite one study that you stand behind, and state the definition of heritability it uses, in your own words or quoting from the study itself.
- araneae 17y agoI didn't call you dumb. I said that your implication was dumb. And it still is. I'm not really sure what you wanted me to get out of that blog post. I did cite a study- I linked to it. And the definition of heritability is still the same.
