Study: The personal need to eliminate uncertainty predicts belief in conspiracy theories

By via PsyPost

Scientists have found that certain psychological predispositions can make people more or less prone to believe conspiracy theories. Now, new research has found another trait that could be linked to conspiracy theories.

The study, published in the European Journal of Social Psychology, suggests that conspiracy theories are associated with the desire to eliminate uncertainties. The study from researchers in Poland and the United Kingdom examined the role of cognitive closure, meaning the tendency to desire an answer for any particular question.

“Why do some people believe that the AIDS virus was created by the US government, that the British security services murdered Princess Diana or that Russians were involved in the Smolensk catastrophe of 2010 that killed the Polish president?” said Marta Marchlewska of the University of Warsaw, the study’s corresponding author. “There is no doubt that conspiracy theories give simple and structured answers to difficult questions. The aim of our research was to find out which psychological traits make people especially prone to adopt conspiratorial explanations and under what circumstances does it occur.”

“We found out that people who are especially motivated to reduce uncertainty by finding clear beliefs about reality and forming quick judgments on a given topic (those high in need for cognitive closure) adopt salient conspiratorial explanations for uncertain events that lack clear official explanations.”

Marchlewska and her colleagues conducted two separate experiments on a total of 700 Polish adults.

Another Study that Doesn’t Show How Acupuncture Works

steven_novellaby via NeuroLogica Blog

The pattern is now quite familiar – a study looking at some physiological outcome while rats or mice are being jabbed with needles is breathlessly presented as, “finally we know how acupuncture works.” As is always the case, a closer look reveals that the study shows nothing of the sort.
electroacupuncture-ratThe current study making the rounds is, “Effects of Acupuncture, RU-486 on the Hypothalamic-Pituitary-Adrenal Axis in Chronically Stressed Adult Male Rats.” We are told that acupuncture has the same effect as pain medication, but honestly I don’t see that anywhere in the study.
The study presents two experiments with rats in which there is a control group, a stress group, stress plus acupuncture, and stress plus sham acupuncture. The first thing to notice is that the rats were not actually getting acupuncture. They were getting the fiction known as “electroacupuncture.” Electroacupuncture is not a real thing – it’s just electrical stimulation through a needle which is called an acupuncture needle.
The authors claim that their results show that electroacupuncture (EA) at the St36 acupuncture point (which is behind the leg), but not sham EA on the back blunt the stress response as measured by cortisol levels, ACTH, and stress behavior in the rats.

The first is that the study is very small, with (in the first experiment) 7 rats in the control and stress groups, and 14 rats in the EA and sham EA groups. That’s not a lot of data points. There is no mention of blinding anywhere in the study. Unless everyone involved in those aspects of the study measuring outcomes were effectively blinded, I see no reason to take the results seriously.
Further, the results are completely unimpressive. The differences are slight. The researchers also pull a common statistical trick. They say, for example, that the difference between control and EA was statistically significant, while the difference between control and sham EA was not. However, they don’t tell us whether or not the difference between EA and sham EA was significant (and by looking at the data I would guess not).

It is possible that this study tells us nothing at all. Given the small number of rats in the study, no documentation about blinding, and the unimpressive results, just a touch of researcher bias (exploiting those researcher degrees of freedom) is all that is necessary to get the graphs to look good enough to publish.
Therefore, regardless of the subject matter, these are preliminary results at best, and unimpressive preliminary results at that.
If we put these results into the context of acupuncture, we then have the equivalent of Bem’s psi research – unimpressive results used to support a massive claim.
Let’s be clear – acupuncture points are a complete fiction.
