I am hesitant to take the lack of the ability to embed as a fact. My impression is that Everett had a theory in mind when he surveyed Piraha and that he sought to confirm his theory. That is, I am worried that this account is subverted by "theory selects data". So I think what we need is a lot more data, ideally collected by someone who the field views as (relatively) neutral.
