Pickens writes "The tendency to falsely link cause to effect — a superstition — is occasionally beneficial, says Kevin Foster, an evolutionary biologist at Harvard University. For example, a prehistoric human might associate rustling grass with the approach of a predator and hide. Most of the time, the wind will have caused the sound, but 'if a group of lions is coming there's a huge benefit to not being around.' Foster worked with mathematical language and a simple definition for superstition to determine exactly when such potentially false connections pay off and found as long as the cost of believing a superstition is less than the cost of missing a real association, superstitious beliefs will be favored. In modern times, superstitions turn up as a belief in alternative and homeopathic remedies. 'The chances are that most of them don't do anything, but some of them do,' Foster says. Wolfgang Forstmeier argues that by linking cause and effect — often falsely — science is simply a dogmatic form of superstition. 'You have to find the trade off between being superstitious and being ignorant,' Forstmeier says. By ignoring building evidence that contradicts their long-held ideas, 'quite a lot of scientists tend to be ignorant quite often.'"

Some superstitions are externally based and come from probability and intuition, not really caring if it's deterministic causation, probabilistic causation or purely co-relational. Others serve the purpose of regulating the internal world, controlling perspectives and where the mind is focused. Self administered psychotherapy, so to speak. Covet not thy neighbours wife, or you will dwell in hell, not because you're going to go there later, but because you're dismissing what you have for what you don't have and putting yourself in hell in your own head, that sort of shit.

As far as I'm concerned the same thing can be said of religion. Thousands of years ago, before we scientifically understood everything, we had religion to give us an inaccurate but constructive understanding of our world and our existence. However now religion has become obsolete and more accurate and scientific things are taking its place. This is obvious to me. I don't understand why all the Republicans don't get it.
Religion wasn't obsoleted by science so much as by disease, at least in the west.
Religion had a firm grip until the Black Plague hit Europe in the Middle Ages.
During that time people felt, with good reason, that the church should be doing its job and getting God to sort it all out.
This didn't happen, so there was a trend towards being less included to obey the church, and the first recorded attack on a monk by members of the public (an unbelievable event at the time).
It didn't help the church that the survivors felt, rightly, that they were entitled to make a lot more decisions on their own about work, pay, housing and such. No longer were they satisfied with doing what they were told and being content with what they had.
Following the plague, whilst religion regained some of its influence, especially in rural area's, its hold was never again universal, and has been in decline since.

There's nothing like having the spires of loads of churches exploded off to make people think a little technology can be a good thing.
Actually, thats not quite fair. The church was never against technology as such, just idea's that challenged their version of the world. Technology usually led to richer states, and therefore a richer church. It was things like 'Earth isn't the centre of the universe' and 'God didn't create the world in 7 days' that gets them twitchy.

Mostly true. It's not so much the belief that God has let you down (there are plenty of excuses for that in Christianity), as a certain attitude of depression and a period in my life where everything was upside down anyway, and a combination of seeing some pretty decnt evidence for macro-evolution (species to species evolution by an organism evolving new abilities). A combination of a number of things are necessary for someone to change their beliefs without being brainwashed.
So I think science and logic helps, but you can't reason someone out of their beliefs. They have to doubt them for themselves, otherwise they will just get very defensive and even more entrenched. You can present some evidence to them and leave it with them to let them compare and decide. It's scary losing your faith, especially if you believe in hell or have a lot of friends with the same beliefs, but it's better than living a lie.

IANAHistorian, but I've been given to understand that faith wasn't diminished by the Black Death, and you'd be hard pressed in the centuries that followed to find anyone in Britain who professed anything other than Christian faith. If anything people became more devout during and after the event - as tends to happen during any crisis. Consider that those who survived probably considered their survival a miracle in the first place...
My understanding is that the economic impact of massive devastation to the working population was the real cause of change. Church and State were almost one and the same during that time, and so the church wielded an incredible amount of power over the daily material lives of the commoners. All land was owned either by the church or by nobles who were closely tied to it, and all workers were essentially beholden to the land-owners to earn a living, grow food etc - and the land-owners pretty much dictated the law and punishment too.
When the population suddenly declined (about a third was lost), there were not enough workers to work the land and such. The balance of power shifted - not massively, but perceptibly - towards the workers. The iron grip was relaxed slightly, and this is what caused the increase in rebellion and unrest. Faith had not diminished, but the power to enforce arbitrary rule had.
It wasn't that the events had shaken people's faith and made them dissatisfied - no doubt they always felt that way. It was that the church/state was somewhat less able to repress their will.

Any given creature wouldn't have enough data or the chance to perform some meaningful experiment. So learning some cause-effect pairs, no matter how flawed, is all that was available and better than nothing.
E.g., if you're a goat and trying to eat one kind of bush gives you some nasty thorn wounds, you just remember that and move on. From now on, you avoid that bush if you can. You don't have the luxury to sample enough such bushes and enough such goats, divided neatly into two groups for a proper double-blind test, to see if you have a good sample. (And probably wouldn't live long if you did.) In practice, maybe that bush was growing through a barbed wire fence, but you wouldn't know that.
The same would apply to the early humans too. If cousing Urgh and aunt Graah ate the funny spotted mushrooms and died, you avoid those mushrooms. You don't divide the tribe in two halves and do a double blind experiment to see if it was really the mushrooms.
So they're not the same, but one of them was all that was available. And we're built to jump to conclusions, basically.

If I understand correctly (and someone please correct me if I'm wrong), the placebo effect is all about subjective measures of benefit. For example, if you give subjects a placebo pill for their back pain, and tell them it's a pain reliever, there's a measurable reduction in reported pain. However, if you give a placebo to people with an objectively measurable problem X, and tell them it's a cure for X, then there's a much smaller effect, or no effect at all.

"There are plenty of examples of flawed superstitious beliefs leading to an equally large disadvantage or equally great damage. "
No doubt but knowing who has truth from who doesn't is a hard problem, science and peer review are are flawed because humans aren't good at detecting what is true from what is not in their own thought processes, concepts and philosophies.
If there were errors in how we think about things (ie. base concepts) then there are errors all the way down. I've been studying this, concepts are the lenses by which people see and interpret the world but few people understand the process by which concepts/knowledge are conceived by a person before they are passed down.
All people operate under tremendous amounts of ignorance, hence Socrates said "All I know is that I know nothing", he knew knowledge was endless.
Socrates often said his wisdom was limited to an awareness of his own ignorance. Socrates believed wrongdoing was a consequence of ignorance and those who did wrong knew no better. The one thing Socrates consistently claimed to have knowledge of was "the art of love" which he connected with the concept of "the love of wisdom", i.e., philosophy. He never actually claimed to be wise, only to understand the path a lover of wisdom must take in pursuing it. It is debatable whether Socrates believed humans (as opposed to gods like Apollo) could actually become wise. On the one hand, he drew a clear line between human ignorance and ideal knowledge; on the other, Plato's Symposium (Diotima's Speech) and Republic (Allegory of the Cave) describe a method for ascending to wisdom.
Socrates believed the best way for people to live was to focus on self-development rather than the pursuit of material wealth. He always invited others to try to concentrate more on friendships and a sense of true community, for Socrates felt this was the best way for people to grow together as a populace. His actions lived up to this: in the end, Socrates accepted his death sentence when most thought he would simply leave Athens, as he felt he could not run away from or go against the will of his community; as mentioned above, his reputation for valor on the battlefield was without reproach.
The idea that humans possessed certain virtues formed a common thread in Socrates' teachings. These virtues represented the most important qualities for a person to have, foremost of which were the philosophical or intellectual virtues. Socrates stressed that "virtue was the most valuable of all possessions; the ideal life was spent in search of the Good. Truth lies beneath the shadows of existence, and it is the job of the philosopher to show the rest how little they really know."

E.g., antibiotics exist only since the 1930's. So only since then you have choices like, basically, "do I trust the doctor and take these pills, or do I trust the shaman and take this extract of Aqua Clara?"
If you go back, say, 5 centuries, already the choices were a lot more like:
A. "Do I trust the alchemist and drink the Aqua Vitae, or do I trust the barber-doctor and let him draw a pint of blood, do I trust the priest and pray real hard to God?" All three were wrong, and actually the first two were _worse_. The alchemists only had distilled alcohol as a cure-all placebo, and drawing blood tended to be worse in the vast majority of cases than doing nothing. So blind faith and superstition might actually have been the better choice in a lot of cases.
B. "Do I trust the superstition that storing pots and dishes with the opening downwards repels evil spirits, or am I an enlightened renaissance man and laugh at such superstitions?" Again, actually the superstition had a point. Dust setting into pots was harmful, and even if nobody had seen a microbe, some people did figure out a correlation between how you store your empty pottery and how often you get sick.
Heck, as late as the 19'th century, during the cholera outbreaks, the superstitious folks had better chances of survival. Mortality in the homeopathic hospitals was actually lower than in the proper medical establishment ones. Of course, homeopathy was still bullshit, but the doctors also bled you dry as the only treatment method they knew, while the homeopaths merely gave you harmless water to drink. (Or rather, solutions of something or another, but so dilluted that they were effectively just water.) The homeopathic solution didn't help, while the other actually caused extra harm to someone already dehydrated and weakened.
Likewise, in the 90'th century, some 50% of the women who gave birth with a doctor would die of septicemic shock, whereas among those who trusted a midwife mortality was a _lot_ lower. Some people actually proposed that doctors wash their hands after performing autopsies on corpses, and before operating or helping people give birth, but that was discounted as a ridiculous superstition. Well, what do you know? The superstitious guys killed a lot less patients. There actually were some nasty germs which the rest got off corpses, and just helped transplant them into previously healthy people.
Etc.
And if you go even further back in time, to when the brain evolved to jump to conclusions and make such hasty generalizations from too little data, the choice was even simple. "I tried to go through this thorny bush, and it hurt for a week. Do I (A) generalize and avoid this kind of bush, or (B) think you can't learn anything from a sample of one, and try again with a dozen other bushes like this?" Or like, "I ate that spotty mushroom and threw up my immortal soul, and was sick for a week. Do I (A) hastily generalize that there's something evil about them, and avoid them, or (B) think it was just a statistically insignifficant coincidence, and try again?"
Simply put, option A was the _safer_ one. Sure, it was sometimes wrong. Sometimes it wasn't the bush, it was the patch of poison ivy it was in. Sometimes it wasn't the mushroom, it was simply an illness which happened at the wrong time. But there was no way to know better anyway. Getting some quick empirical cause-effect rules was the best you could do.
Option B wasn't that safe at all. A lot of time trying something harmful again, just to see if you got the cause right, would outright get you killed.
Don't get me wrong. I'm not against science or medicine or anything. Sure, _nowadays_ that's a better choice than superstition and empirical generalizations. Very much so. But the interval where we even had that choice at all is infinitesimal, at evolution scales. We had medicine for less than 100 years, the human species alone is 200,000 years old.

The cost of continuing to avoid such foods, even when we understand the science and can prepare them safely is minimal.
However, there are times when the refusal to understand explanations behind superstitions cost our ancestors dearly. Take cats. Cats coexisted with ancient man as efficient means to keeping rodents out of grain stores. After a time, some civilizations came to hold cats in high regard, even worship them. Ancient Egypt is one example. Enter Christianity. Rather than examine the basis of other religions and cultures reverence for the cat (understanding their practical utility shouldn't have been that hard, even in the middle ages), they associated cats with pagan religions and eventually witchcraft.

Executive summary:
Neuropsychology student is studying split-brain patients- people with injuries or diseases that inhibit the hemispheres of the brain from communicating. Their brains function normally kind of, except no information is passed between the two hemispheres.
Speech, or more specifically, translating what you see into words, is predominantly handled by your left hemisphere. Your left visual field is handled by your right hemisphere, and your right visual field by your left.
One experiment he conducted was showing different pictures to each eye at the same time, and then asking the subject to point to a card showing a picture that relates to the image shown.
One subject was shown a picture a picture of a chicken claw to his right eye (left hem.), and a snow covered landscape to his left (right hem.). The subject then pointed to a chicken with his right hand (again, controlled by left hem), and a shovel with his left (right!). Obviously, the logic behind his choice was the claw belongs to a chicken, and you need a shovel to shovel snow. However, when asked to explain his choice, the subject responded with something to the tune of, "The claw belongs to a chicken, and you need a shovel to clean the chicken shed."
Even though acting independently he was able to correctly deduce the response, the lack of communication between the hemispheres meant that when his left hemisphere was trying to put it all into words, it was unable to recall why he chose the shovel from the right hemisphere of the brain.
Gazzaniga (the student conducting the test) believes that in the left hemisphere of the brain lies what he calls the interpreter: a part of your brain whose sole function is to try to rationalize what we do not understand. An evolved speculation machine. Like the article said, I probably served an evolutionary purpose in that it kept us paranoid and safe in the grasslands, but odds are this is also the same part of the brain that saw lightning and concluded there must be an unseen humanoid in the sky making it. Or, when the great questions of "why?" and "how?" concerning our world began to plague the mind, the same brainpiece reached the same god conclusion.

When he didn't seem phased by that, I told him that his toy could fall out of the open door and be lost. He got very frightened and promised not to do that again. (He hasn't.) Why the different reaction? I think that falling out of a car and being seriously hurt is an abstract concept to him. He just can't really imagine what it would feel like. But losing a toy that he likes, that he can easily imagine. Sometimes with kids the bigger threat isn't the one that they can wrap their minds around and thus isn't the scarier option.

As Richard Feynman once said "Science is the belief in the ignorance of the experts"
He also had this comment in his classic speech "Cargo Cult Science"
I don't think I'm as optimistic as Feynman that it's only a small group of scientists that don't have "that kind of disease"...
