Please note that this website is currently a work in progress! Lots of interesting data and statistics to come.
Overall a good lecture, but it was painful to watch him deride Penrose & Hameroff's theory by saying they basically just connected QM and consciousness by saying "QM mysterious, consciousness mysterious, so they must be related" and then later all but admit (unwittingly, apparently) that the role of the observer is central to QM and that that clearly implies a close connection between consciousness and QM. Maybe he was just playing the gallery, but even if he was, it's a shitty, anti-scientific attitude to propagate regardless.
Quantum mysticism is just another example of we-don't-understand-it-so-it-must-be-magic approach to learning about the world. Consciousness is what brain does. It's a macro world of chemical compounds and electricity. Quantum mechanics a micro world measured in Planck lengths 33 orders of magnitude smaller than the dot at the end of this sentence.
While I find quantum mechanics very intriguing, consciousness is just thoughts, a mechanism which evolved as a way to find food and reproduce.
It so happens that sometimes legitimate scientists like Bohm or Penrose stray into the pseudoscience territory. As to looking into the connection, how? Where would you start? There are hundreds, if not thousands, of variations of the double slit experiment. There are thousands of quantum entanglement experiments done every year. How and where would you insert consciousness? I'm not interested in talking about it, I'm not into philosophy or religion. I'm interested in data.
