Post Hoc

Hypothesizing after the results are known, or HARKing, occurs when researchers check their research results and then add or remove hypotheses on the basis of those results without acknowledging this process in their research report ( Kerr, 1998 ). In the present article, I discuss 3 forms of HARKing: (a) using current results to construct post hoc hypotheses that are then reported as if they were a priori hypotheses; (b) retrieving hypotheses from a post hoc literature search and reporting them as a priori hypotheses; and (c) failing to report a priori hypotheses that are unsupported by the current results. These 3 types of HARKing are often characterized as being bad for science and a potential cause of the current replication crisis. In the present article, I use insights from the philosophy of science to present a more nuanced view. Specifically, I identify the conditions under which each of these 3 types of HARKing is most and least likely to be bad for science. I conclude with a brief discussion about the ethics of each type of HARKing.

Abstract Objectives Athletes subscribe to different energy and macronutrient intakes based on the needs of the sport. The aim of our study was to evaluate total energy and macronutrient intakes between different types of Masters athletes. Methods Female and male Masters athletes participated in this cross-sectional study. Dietary consumption data were measured using Block's 2005 Food Frequency Questionnaire. A one-way analysis of variance was used to compare total energy, protein, carbohydrate, and fat (in grams [g]) intakes among the athletes. When significant differences were found, a Fisher's LSD post hoc test was performed to identify specific group differences. The significance level was set a priori at P < 0.05. Results A total of 330 athletes (182 women and 148 men) were included in the study. Participants were 36.55 ± 11.2 years of age. The athlete population consisted of general athletes (n = 81), runners (n = 116), triathletes (n = 53), rowers (n = 46), and CrossFit athletes (n = 34). Runners (1941.35 ± 697.25 kilocolaries [kcal]), triathletes (2031.65 ± 912.02 kcal), and rowers (2004.15 ± 978.42 kcal) all had significantly greater total energy intakes compared to CrossFit athletes (1538.80 ± 491.74 kcal) (P < 0.05). Runners (226.21 ± 89.67 g) and triathletes (235.43 ± 134.29 g) had significantly greater carbohydrate intakes compared to CrossFit athletes (162.93 ± 66.99 g) (P < 0.05). Rowers (83.31 ± 44.74 g) had a significantly greater protein intake compared to CrossFit athletes (64.77 ± 21.32 g) (P = 0.027). Rowers (87.35 ± 45.91 g) had a significantly greater fat intake compared to CrossFit athletes (68.86 ± 25.10 g) (P = 0.041). Conclusions Based on our data, runners, triathletes, and rowers all had greater total energy intake compared to CrossFit athletes. Rowers also consumed significantly more protein and fat than CrossFit athletes. Rowers may consume more protein and fat due to the combination of endurance and strength needed to meet the demands of the sport. Further research is needed to continue evaluating total energy and macronutrient intakes between different types of Masters athletes. Funding Sources This project was unfunded.

As If

This article considers a practice in scientific communication termed HARKing (Hypothesizing After the Results are Known). HARKing is defined as presenting a post hoc hypothesis (i.e., one based on or informed by one's results) in one's research report as if it were, in fact, an a priori hypotheses. Several forms of HARKing are identified and survey data are presented that suggests that at least some forms of HARKing are widely practiced and widely seen as inappropriate. I identify several reasons why scientists might HARK. Then I discuss several reasons why scientists ought not to HARK. It is conceded that the question of whether HARKing's costs exceed its benefits is a complex one that ought to be addressed through research, open discussion, and debate. To help stimulate such discussion (and for those such as myself who suspect that HARKing's costs do exceed its benefits), I conclude the article with some suggestions for deterring HARKing.

William Whewell’s two seminal works, History of the Inductive Science, from the Earliest to the Present Time (1837) and The Philosophy of the Inductive Sciences, Founded upon their History (1840), began a new era in the philosophy of science. Equally critical of the British ‘sensationalist’ school, which founded all knowledge on experience, and the German Idealists, who based science on a priori ideas, Whewell undertook to survey the history of all known sciences in search of a better explanation of scientific discovery. His conclusions were as bold as his undertaking. All real knowledge, he argued, is ‘antithetical’, requiring mutually irreducible, ever-present, and yet inseparable empirical and conceptual components. Scientific progress is achieved not by induction, or reading-out theories from previously collected data, but by the imaginative ‘superinduction’ of novel hypotheses upon known but seemingly unrelated facts. He thus broke radically with traditional inductivism – and for nearly a century was all but ignored. In the Philosophy the antithetical structure of scientific theories and the hypothetico-deductive account of scientific discovery form the basis for novel analyses of scientific and mathematical truth and scientific methodology, critiques of rival philosophies of science, and an account of the emergence and refinement of scientific ideas.

This study tests whether playing violent video games leads to desensitization and increased cardiovascular responding. In a laboratory experiment, 42 men spent 20 min playing either a high- or low-violence version of a “first-person shooter” game. Arousal (heart rate, respiration rate) was measured continuously. After playing the game, emotional responses to aversive and aggressive stimuli - pictures from Lang, Bradley, and Cuthbert’s (1999) International Affective Picture System - were assessed with self-ratings and physiological measurement (skin conductance). Results showed no differences in the judgments of emotional responses to the stimuli. However, different effects of game violence emerged in the physiological reactions to the different types of stimulus material. Participants in the high-violence condition showed significantly weaker reactions (desensitization) to aversive stimuli and reacted significantly more strongly (sensitization) to aggressive cues. No support was found for the arousal hypothesis. Post-hoc analyses are used to discuss possible moderating influences of gaming experience and player’s trait aggressiveness in terms of the General Aggression Model ( Anderson & Bushman, 2001 ) and the Downward Spiral Model ( Slater, Henry, Swaim, & Anderson, 2003 ).

Kantian Philosophy

Abstract The main thesis of this paper is that Pap’s The Functional A Priori in Physical Theory and Cassirer’s Determinism and Indeterminism in Modern Physics may be conceived as two kindred accounts of a late Neo-Kantian philosophy of science. They elucidate and clarify each other mutually by elaborating conceptual possibilities and pointing out affinities of neo-Kantian ideas with other currents of 20th century’s philosophy of science, namely, pragmatism, conventionalism, and logical empiricism. Taking into account these facts, it seems not too far fetched to conjecture that under more favorable circumstances Pap could have served as a mediator between the “analytic” and “continental” tradition thereby overcoming the dogmatic dualism of these two philosophical currents that has characterized philosophy in the second half the 20th century.

AbstractAccording to a widespread view, the essentials of Kant’s critical conception of space and time as set forth in the Transcendental Aesthetic can already be found in his 1770 Inaugural Dissertation. Contrary to this assumption, the present article shows that Kant’s later arguments for the a priori intuitive character of our original representations of space and time differ crucially from those contained in the Dissertation. This article highlights profound differences between Kant’s transcendental and his pre-critical conception of pure sensibility by systematically comparing the topic, method and argumentation of the First Critique with that of the Inaugural Dissertation. It thus contributes to a better understanding of the Transcendental Aesthetics itself, which allows one to distinguish its peculiar transcendental mode of argumentation from considerations made by the pre-critical Kant, with which it can easily be conflated.

Elective Tracheostomy

AbstractThe number of critically-ill coronavirus disease 2019 (Covid-19) patients requiring mechanical ventilation is on the rise. Most guidelines suggest keeping the patient intubated and delay elective tracheostomy. Although the current literature does not support early tracheostomy, the number of patients undergoing it is increasing. During the pandemic, it is important that surgeons and anesthesiologists know the different aspects of tracheostomy in terms of indication, procedure, tube care and complications. A literature search was performed to identify different guidelines and available evidence on tracheostomy in Covid-19 patients. The purpose of the present article is to generate an essential scientific evidence for life-saving tracheostomy procedures.
