The speaker characterizes integrated information theory as a non-functionalist attempt to explain consciousness, rather than explaining it through the activity of its smaller parts.

“uh, pseudoscience-y attempts to do this, which basically, uh, do things that are formally unsound. And for me, the issue with, uh, uh, integrated information theory is that it's an attempt to make a theory that is not functionalist and which means it's not explaining it by something that the smaller parts are doing.”
