I confess I had fun reading this book. It filled me with shock, indignation and incredulity. I enjoyed the intellectual challenge of reading a book against the institution of science, and trying to defend science against both legit and absurd claims. My attitude going in was “ok, let’s see what you got”, and my attitude throughout ranged from “that’s fair” to “He’s f*cking crazy...”. When I described passages to my boyfriend, he would just ask “are you sure he’s not just a troll?”
Who should read this book? Almost no one. The author does not offer a reasonable alternative to mainstream science, all of his most legitimate criticisms of science is well treated in other books, where it is not juxtaposed with tinfoil hat theories (slight, but only slight, exaggeration). Even scientists looking for healthy criticism to their own dogmas should look elsewhere (recently read Lost in Math, which is a good criticism of physics for example). The main value of this book, to me personally, is just the awe inspiring contradiction of someone who can understand a good chunk of science, and also thoroughly believe psychic phenomenon, and just watch as he bends over backwards and into a pretzel trying to fill the holes of science with his crazy. It’s pretty amazing how he tries to explain standard psychic things (mind reading, alternative medicine, chakra) with science speak. He even has a chapter about common bad practices in science; without really realizing how tarnished his own field of pseudoscience really is.
The book has an interesting structure. Every chapter deals with an issue, first explaining how mainstream science tries to explain things, then how it tries to explain something unsuccessfully (like consciousness or the origin of the universe) revealing internal contradictions, and then providing an alternative explanation that is self evidently superior, usually coming down to “morphic resonance”. Then it ends with “questions to materialists” which I quite enjoyed answering, and a little summary which I never read.
Before going into what was wrong in this book, I’d like to start with what was right. The author did a surprisingly good job of explaining mainstream science; not always right but when you are covering EVERY field, there’s no way to be 100% accurate (although often where he was wrong was exactly where his critical reasoning failed). He also really did identify some serious problems in our current understanding of things; we have no idea how consciousness works for example. Also, if nothing else, his alternative hypotheses are actually often testable, which isn’t always the case with pseudoscience.
It’s also important to specify that not all of his theories are detached from reality, or at least current standard science. His idea that memories are a form of “resonance” of past brain activations is really just a more poetic way of saying what neuroscientists believe to be how memory works. I’m not quite sure why he hasn’t noticed this.
As for what was wrong: his own alternative ideas. A) Sometimes they were wrong in ways that you could just measure, but often times he was B) wrong because of the framework within which he operated. This makes for an interesting way of being wrong, because he’s not technically wrong anymore, but he’s just no longer accurate. C) He was sometimes so wrong but not dealing with clearly defined parameters, so less easy to test. Often though, you could just think things through to realize how wrong they were. D) sometimes he just became incoherent, but I won’t deal with that, I couldn’t say for sure if it was him or me.
Regarding A, this was the most surprising part. He has various academic degrees, more importantly actual experience in experimental science, and yet he would give an explanation that is easily disproven. There was one particular instance that fell squarely in the scope of my competences: neuroscience. A famous study by Libet had participants look at a clock face with just a seconds hand, and whenever they felt like it, they had to push a button, and tell the experimenter at what angle the clock dial was at when they made the decision. This then allowed the researchers to see that the moment participants thought they made the decision was actually over a second after their EEG had started to activate in preparation. Most of the world took this to mean that decisions are made subconsciously, and what we perceive as our conscious mind is not really the most “up to date” version of what our brain has decided. Some believe that it’s a sign that consciousness has no use at all. But Sheldrake here has a different idea. He thinks that this marks evidence that the MIND CAN AFFECT THE PAST! Basically the mind’s causality can work backwards in time! Woooo! The funny thing about that is, we can prove it’s wrong. Just have a participant make choices based on a stimulus you provide, and try and predict the choice before the stimulus has been shown! There are a lot of ways to salvage the role of consciousness in the original Libet experiment without resorting to unraveling the main principle of causality.
B) Science is about trying to find relationships in nature and ourselves that allow us enough understanding to predict what will happen, or at least what could happen. We know that we are severely limited by the cognitive capacity of our brains, an organ not designed for science, and by our sensory organs. So we create models to simplify things just enough to make sense out of them, and science is a quest to create more and more useful models that match reality as best it can. A simple case in point: you can define space with Euclidean coordinates, thinking of everything as a flat plane; but it takes a different kind of spherical geometry to actually launch rockets into space, because that’s a slightly better representation of space, especially at that scale.
Likewise, we could interpret all matter as fire, earth, water, air and ether, either warm or cold, like Aristotle. But that’s not quite as informative as having atoms arranged as elements, with different phases of matter based on temperature and pressure. And likewise following Sheldrake, we could just interpret everything as having a “purpose”, with planets having the purpose to maintain their orbit, crystals having the purpose to crystallize, and trees have the purpose of growing; but this is not quite as informative as saying “purpose” is a human concept like “justice”, that reflects how we as individuals have goals and a desire for meaning, and animals can have a very similar mental state, like the purpose of building a nest; but trees don’t have a purpose, they have growth, and that growth is determined by an interaction of genes and the environment, which is different from how crystals grow which is based on just environment. Sheldrake wants to explain everything in terms of morphic resonance, and how there’s some sort of collective memory and collective goal for a given species or category of object in nature, but a framework that has everything have purpose is just not useful to explain substantially different phenomenon.
C) Most of Sheldrake’s misconceptions would have been clarified with just a bit more imagination on his part. This is actually true of most conspiracy theorists, fringe science, and religion. Instead of trying to interpret everything that exists according to your theory, try looking at your theory and see what it would predict, and then see if that exists in the real world, if not, how much do you have to modify your theory until it’s explained away? A well defined theory can be dismantled quickly like this. A clear cut example is one of the first chapters, in which the author tries to argue that its possible for some individuals to go years without eating because they can tap into some other energy field that physics has not yet discovered or properly investigated in the context of physiology. Aside from there being no molecular/cellular explanation as to how this could happen, you have to look at the larger ramifications of a whole new energy source. There should be WAY more “impossible” events, life in unexpected places, plants surviving in the darkness, etc. not because the phenomenon has to be common per se, but from the sheer magnitude of life on earth; if there’s even a 0.1% increase in energy entering a biological ecosystem, it shows! Case in point, he thinks it’s more reasonable that people who claim to never eat are tapping into an energy field than the alternative, that most are being dishonest, others have amazing metabolisms, and some could be getting energy from mundane sources, like not clean water. But instead of trying to investigate 1 in a billion cases of obscure Indian gurus, why not first explain why millions of people die from starvation at all? Sure they may not all have found a way to access this energy source, but that requires proper explanation as to why some do and some don’t. And why aren’t these gurus teaching all the hungry people how to do it? And there he reaches the point of ill defined hypotheses; when you don’t have a mechanism to explain these exceptions, you’re free to invent all sorts of post hoc reasons why most of humanity and animals starve without food.
The broader point is that most of these mystic explanations would have much larger consequences than just tiny fringe exceptions. The saying is that big claims require big evidence, this is what it’s referring to; you can’t change fundamental principles based on few unusual cases when doing so would necessarily drastically change everything else, in ways we just don’t observe. This is how scientists have hypothesized dark matter and dark energy; it’s not explaining tiny unexpected measurements like a single planet’s speed, it explains massive effects, that are everywhere in the universe, just not at a scale we usually have access to, which is why it’s still mostly unknown. So science has a special place in its heart for mystery forces that we don’t usually observe, it would have loved for there to be additional invisible fields through which it’s possible for living organisms to survive without nutrition, but things on the scale affecting humans are necessarily waaay more obvious than distant dark matter or tiny quantum physics, and we should have seen it by now, systematically.
He also does poor science. He has a whole self righteous section on blindedness, and how most fields don’t do blind testing in more than 10% of publications, except somewhat medical science at 30%. This I am really confident is false, because I would estimate that 90% of the papers I’ve read in psychology and neuroscience used blinded methods, and most peer reviewed journals demand it. So I don’t know what he did wrong to get such a wrong sample of papers, but a good starting point is that his “meta-analysis” only included 1500 papers. To put that into context, there are around 7 million scientists in the world right now, each expected to publish at least 1 article per year. The fraction of papers he looked at is so small it’s suspicious. Sure he did this in the 90s where you had to do meta analyses by hand, but that doesn’t make the results any more reliable.
I didn’t dedicate the time to evaluate all of the examples, anecdotes and studies he cites that “prove” his crazy theories, but the ones I did look at, and the above example, gave me the overall impression that he just does not have a good grasp of statistics, which is a failing of the whole pseudoscience “field”.
There’s so much more to be said, but I don’t think it’s really worth my time.
