Many magical thinkers oppose research findings falsifying their claims. Are such folks correct, at least in part? Click on the two links below for videos that do a good job of objectively analyzing Bayesian probability calculations and research study findings in general:
Human knowledge has progressed exponentially since the dawn of modern science. It is no longer reasonable to accept claims without sufficient objective evidence. The harm from religion, alternatives to medicine, conservatism, and all other false beliefs will be exposed on this blog by reporting the findings of science. This blog will also reinforce what should be the basics of education: History, Civics, Financial Literacy, Media Literacy, and Critical/Science Based Thinking.

Good Research Is Hard To Find
My summary of science-based thinking is: question claims; demand objective evidence; think critically (in that order). Unfortunately, even scientists frequently misuse the scientific method. The link below presents the details involved with scientific research and how it can be in error either through mistake or conscious fraud:

Tricks Regarding Alternatives To Medicine "Research"
"Alternative medicine is an area that is now beginning to attract a
reasonable amount of research. If we cast a critical eye on what emerges
from it, we are bound to be harshly disappointed. The journals of
alternative medicine are full of studies apparently showing that this or
that alternative therapy is efficacious. Yet there are several
compelling reasons to be sceptical about such findings. Much of what is
being published in this area is hardly worth the paper it is printed on,
and many of the researchers of alternative medicine are
pseudo-scientists who seem about as trustworthy as a £4 note."

A "Manhattan Project" For Understanding The Brain
"Punching through to the next level of understanding of how our brains
work may just require this level of collaboration. Obviously, not every
research question is this complex and will require such a model. The big
questions of science, however, likely do."

Replication Of Studies A Key Component Of Research
"One very dominant pattern that I see on a frequent basis is the tendency
to cite preliminary evidence as if it is rock-solid and confirmed.
People will worry about the health effects of GMOs or vaccines because
of a few flawed studies. They will promote the health benefits of a
supplement based upon a preclinical study that is many steps removed
from actual clinical claims. They will accept a new phenomenon as real
based on studies that have never been replicated."

Nutrition Activists Go After American Diabetes Association, CDC And Everyone Else
"We're not picking and choosing science and health positions based on
donors or their marketing or lobbying agendas, inadvertently or not. If
we mollified our statements based on that we wouldn't be the trusted
consumer advocates we are (2) and we wouldn't get donations from the
public. Some shills can be funded - U.S. Right To Know is 97 percent
funded by organic food corporations who pay them to scaremonger
genetically modified foods - but individuals won't give you money if
they don't like your work and believe in your mission."

Good Health And Nutrition Advise Available
"What caught our attention was the results of a survey run by the Independent Women's Forum that found:
- '83 percent of women said they have trouble telling the difference between a legitimate scientific study and one designed to scare them; and
- 87 percent of women say they have a tough time finding sources for health and wellness information that they can trust.'
While we have no further information about the reliability of this survey or its generalization, these figures surprised us, and motivated us to reprint some advice about who to trust, and who not to trust."

Research Studies Have Probability Wrong
"The problem is that the p-value gives the right answer to the wrong question. What we really want to know is not
the probability of the observations given a hypothesis about the
existence of a real effect, but rather the probability that there is a real effect – that the hypothesis is true – given the observations. And that is a problem of induction"

Watch For Unscientific Methods In Polling
"One of the keys to successful social science is to ask unbiased survey
questions*. The lack of a control group is just sloppiness. Gallup
should know better."

A Better Way Of Evaluating Chiropractic Effectiveness
"The research on chiropractic has been far from rigorous. One of the
problems is that studies of spinal manipulation therapy (SMT) can’t be
double blinded, and it is very difficult to even do single blinding. So
most studies resort to non-manipulation control groups like “usual care”
or “wait list” or “pain medication.” Those studies are practically
guaranteed to lead to false positive conclusions: they make SMT look
more effective than it would look if you could provide a control that
patients couldn’t distinguish from real SMT."

Why Nutrition Is A "Soft Science"
"Of course, this type of clinical trial isn't suited to most
nutritional research. Simply altering intake of one food or another
doesn't take into account the rest of the diet, and again, accurate
quantities are hard to come by. A well-controlled study of intake on a
metabolic ward (a hospital or clinic where participants in a study might
live or get all their foods), for example, involves actually weighing
the foods, whose composition has been scientifically determined,
given to participants. Any foods a person doesn't eat are weighed again,
and the amount actually consumed can be determined by the difference.
Obviously, this isn't conducive to learning what free-living people
really eat.
"Unless and until we develop solid means of determining what people really eat, I'm afraid we're bound to continue to find contradictions in nutrition research."

Private Investment In Research
"While the stated goal is both vague and overly ambitious, and the amount
of funding is actually modest when compared to existing funding for
medical research, I am actually a bit optimistic about the Chan
Zuckerberg Initiative and projects like Biohub."

Oh, by the way, Zuckerberg is an atheist. So much for the need for religion to do good.

Weather And Pain
"t is nearly 2,500 years since the
Greek physician Hippocrates noticed a connection between pain and the
weather, but scientists have shown that it may well be true."

Football Decisions Are Not Science-Based
"Massey, Thaler, and Romer's works have been known for more than a
decade, but NFL football coaches and owners still show near universal
hesitance to adopt their advice. For all its high stakes, pro football
is very much a conservative sport. Tradition trumps reason. Football is
powerful, irrational, and instinctual, with an almost animal magnetism.
Perhaps that's what keeps us watching."

Absence Of Evidence IS Evidence Of Absence
"Absence of evidence, or the failure to observe evidence that favors a hypothesis, is evidence against
that hypothesis. This is because we are significantly more likely not
to see evidence for a hypothesis when it is false than not to see it
when it's true — some assertions demand that the universe be screaming
with supporting evidence, so when that evidence is not actually
observed, it counts against it."
(NOTE: This is true when an hypothesis has been thoroughly investigated)
If evidence is lacking when we expect it to be abundant, then it very much allows us to dismiss a hypothesis.

The Odds Of Dying From Events
"The National Safety Council publishes an “Odds of Dying Chart” that
affirms we are more likely in our lifetime to be killed by everyday
activities - and they would like to prevent that, which is why they
publish a probability of events. Accidental death is far more likely
than being murdered by a gun. There is a 1 in 144 chance of dying from a
fall compared to 1 in 6780 from severe thunderstorm, and a 1 in 470
chance of dying in a car as opposed to 1 in 164,968 chance of a
lightning strike."

Research Fraud At Duke Piles Up
"Duke officials took a closer look at her work and didn't like what they
saw. Fifteen of her papers, mostly dealing with pulmonary biology, have
now been retracted, with many notices citing "unreliable" data. Several
others have been modified with either partial retractions, expressions
of concern, or corrections. And last month, a U.S. district court
unsealed a whistleblower lawsuit filed by a former colleague of
Potts-Kant."

Challenges To Scientific Research Not Published
"The authors believe that one way to address this problem would be to
link to rebuttals in the original papers so that readers understand that
the paper is contested."
