Many of the examples in the table (especially “values,” “bias,” and “error”) aren’t the result of a knowledge gap, but of a simple definitional dispute.
It’s not clear to me which is the case, actually. It would be difficult to dispute the assertion that the average layman is almost always primed to read “positive” as “good” rather than “present” or “upward,” but that doesn’t indicate whether or not he’s actually aware of those alternate uses. Maybe he’s never been exposed to scientific literature—that wouldn’t exactly be shocking.
I wish I could access the original paper the table was published in. Alas!
I’m not sure how valid your point is in practice. Being enthusiastic about hunting does not necessarily indicate a willingness to face the consequences of one’s actions, nor does it indicate any particular attitude toward factory farming. It may just indicate a lack of visceral discomfort when encountering animal suffering.
It is plausible that some/many/most hunters simply enjoy pursuing and eating prey, and that the comparative advantages to overall utility make little or no difference to them. In this case, I wouldn’t say that the utility advantage says anything positive about the individual’s character, but I certainly do think it’s fortunate that self-serving behaviors can occasionally lead to greater overall utility.
(Note: I’m sure there are hunters who subsist on hunted meats because they find mainstream meat production ethically appalling. I just doubt that they’re representative of all hunters.)
