This reminds ds me of when my 2nd grade teacher told me that pers don't have emotions. She said we simply ascribe human characteristics to things we don't understand.

Just because a thing hasn't been emperically proven to exist doesn't mean we should assume that it does not exist.

Medicine makes this mistake with prevalence. Often, as with celiac disease, Graves' disease, Sjogren's and other autoimmune diseases, lack of awareness leads to a dearth of diagnoses which is too-often confused with prevalence.

It's unsettling to see that some scientists proceed as though they know everything knowable.
