A letter by distinguished scientists sought to discredit a leading theory of consciousness as pseudoscience. That was mistake. No theory of consciousness is currently empirically testable, so strictly speaking, no such theory is scientific, argues Erik Hoel.
Last week, over one hundred scientists, many prominent or even world-famous, debuted a signed letter declaring that one of the most popular scientific theories of consciousness is “pseudoscience.” The letter is directed at Integrated Information Theory (IIT), and its signers go so far as to say that:
“As researchers, we have a duty to protect the public from scientific misinformation.”
Sparked by the recent press around an international “adversarial collaboration” that pitted the predictions of theories of consciousness against one another, the letter is quite short, just a few paragraphs, and the number of signees outweighs the number of citations by an order of magnitude. Yet the names include many well-known researchers in the field, such as Hakwan Lau, Joseph LeDoux, Bernard Baars, Patricia Churchland, Daniel Dennett, and Keith Frankish, along with plenty more (although there are noticeable absences).
