The p-value ritual

The p-value and its implicit symbolism

The Aristotelian conditional syllogistic logic behind the Fisherian p-value is widely misunderstood which leads to fallacious logical inferences. The p-value resembles a Kantian paralogism, i.e., it appears objective and logically valid even though it is not. The p-value is an irrational social ritual (cf. Gigerenzer, 2004). Social conformity, obedience to authority, groupthink, and other aspects of Social Identity Theory (SIT) play an important role in this context.

Given the well-documented paralogisms associated with classical Fisherian null hypothesis significance testing (cf. Cohen, 1994) I advocate alternative inferential research methods. For the statistical analyses of the experimental data I collected during my PhD I utilised Bayesian bootstrapping, Bayes Factor analysis, and Bayesian parameter estimation via Markov chain Monte Carlo simulations (in addition to classical NHST).

“Few researchers are aware that their own heroes rejected what they practice routinely. Awareness of the origins of the ritual and of its rejection could cause a virulent cognitive dissonance, in addition to dissonance with editors, reviewers, and dear colleagues. Suppression of conflicts and contradicting information is in the very nature of this social ritual.”

A CT scan providing evidence of the nasal cycle. The more patent airway is on the right of the image; the swollen turbinates congesting the left.

The nasal cycle is unknown to many people. It refers to the alternating partial congestion and decongestion of the nasal cavities in primates. It is a visible physiological congestion of the nasal conchae (nasal turbinates) due to selective lateralised activation of one half of the autonomic nervous system by the hypothalamus (cf. hemispheric lateralisation). It completly unrelated to pathological nasal congestion and is comparable to the circadian rhythm (in the broadest sense). The ancient yoga literature describes the nasal cycle in detail and it is the focus of several pranayama (breathing) techniques which have the goal to balance the nervous (...)

Vastra Dhauti

A strip of wet cloth, four angulas wide (3") and fifteen hands (1¼ metres) in length, is stoutly swallowed and, then taken out, as instructed by the guru. This is known as dhauti.
~ Hatha Yoga Pradipika 2.24

Escherichia coli, one of the many species of bacteria present in the human gut.

Vastra is Sanskrit for "cloth" and dhauti means "washing". It is a yogic technique designed to cleanse the inner body, specifically the GI tract. It is one of several types of purifying dhauti methods in which a long strip of cotton cloth is ingested and then pulled out to cleans and detoxify the intestines. Given the fact that our environments contain countless (chemical) toxins which are responsible for various "pathologies of civilisation"  it is important to explore and practice methods to detoxify (...)

Decentralised network systems of trust: Blockchain technology for scientific research

An interesting and innovative proposal is to use blockchain technologies (usually associated with digital crypto currencies like, for instance, Bitcoin or Ethereum) to counteract the replication crisis, to validate empirical findings, and to improve and optimize the scientific procedure on a large scale (Bartling & Fecher, 2016). The authors suggest that “Blockchain could strengthen science's verification process, helping to make more research results reproducible, true, and useful” (Bartling & Fecher, 2016, p. 1). Even though this proposal might seem unrealistic or overstated to those unfamiliar with blockchain technologies, we think that this is indeed an excellent innovative and creative proposal because blockchain technologies can be used in all situations which require (...)
