Allan Crossman calls parapsychology the control group for science. That number tells you how many people will recover whether the drug works or not. That number tells you how many studies will discover positive results whether the phenomenon is real or not.

Trying to set up placebo science would be a logistical nightmare. The results are pretty dismal. Parapsychologists are able to produce experimental evidence for psychic phenomena about as easily as normal scientists are able to produce such evidence for normal, non-psychic phenomena.

As Eliezer Yudkowsky puts it: Parapsychologists are constantly protesting that they are playing by all the standard scientific rules, and yet their results are being ignored — that they are unfairly being held to higher standards than everyone else.

It just means that the standard statistical methods of science are so weak and flawed as to permit a field of study to sustain itself in the complete absence of any subject matter.

These sorts of thoughts have become more common lately in different fields. Psychologists admit to a crisis of replication as some of their most interesting findings turn out to be spurious. And in medicine, John Ioannides and others have been criticizing the research for a decade now and telling everyone they need to up their standards.

But there is broad agreement among the most intelligent voices I read 12345 about a couple of promising directions we could go: Demand very large sample size. Demand replication, preferably exact replication, most preferably multiple exact replications.

Trust systematic reviews and meta-analyses rather than individual studies. Meta-analyses must prove homogeneity of the studies they analyze. Use Bayesian rather than frequentist analysis, or even combine both techniques. It is far too easy to massage p-values to get less than 0.

Require pre-registration of trials. Do heterogeneity analyses or at least observe and account for differences in the studies you analyze. Demand randomized controlled trials. Stricter effect size criteria. Well, what now, motherfuckers? Everyone had a lot of criticisms, some of which were very very goodand the study failed replication several times.

By my count, Bem follows all of the commandments except [6] and [10]. And he apologizes for the small effect size but points out that some effect sizes are legitimately very small, this is no smaller than a lot of other commonly-accepted results, and that a high enough p-value ought to make up for a low effect size.

This is far better than the average meta-analysis. Bem has always been pretty careful and this is no exception. Yet its conclusion is that psychic powers exist.

So — once again — what now, motherfuckers? In retrospect, that list of ways to fix science above was a little optimistic. The first nine items large sample sizes, replications, low p-values, Bayesian statistics, meta-analysis, pre-registration, publication bias, heterogeneity all try to solve the same problem: Bem definitely picked up a signal.

None of these commandments even touch poor experimental technique — or confounding, or whatever you want to call it. If an experiment is confounded, if it produces a strong signal even when its experimental hypothesis is true, then using a larger sample size will just make that signal even stronger.

Replicating it will just reproduce the confounded results again. Low p-values will be easy to get if you perform the confounded experiment on a large enough scale.

Pre-registration only assures that your study will not get any worse than it was the first time you thought of it, which may be very bad indeed.

Searching for publication bias only means you will get all of the confounded studies, instead of just some of them.They can be the most important components of your application—the essays.

However, if you are discussing, for example, the historical context in which the episode originally aired, you should cite the full date.

Because you are specifying the date of airing, you would then use WB Television Network (rather than Mutant Enemy), because it was the network (rather than the production company) that aired the episode on the date you’re citing.

Soil health, along with water supply, is the most valuable resource for humans, as human life depends on the soil’s generosity. Soil degradation, therefore, poses a threat to food security, as it reduces yield, forces farmers to use more inputs, and may eventually lead to soil abandonment. Unfortunately, the importance of preserving soil health appears to .
