Public misconceptions about dyslexia: The role of intuitive psychology.

ABSTRACT: Despite advances in its scientific understanding, dyslexia is still associated with rampant public misconceptions. Here, we trace these misconceptions to the interaction between two intuitive psychological principles: Dualism and Essentialism. We hypothesize that people essentialize dyslexia symptoms that they anchor in the body. Experiment 1 shows that, when dyslexia is associated with visual confusions (b/d reversals)-symptoms that are naturally viewed as embodied (in the eyes), laypeople consider dyslexia as more severe, immutable, biological, and heritable, compared to when dyslexia is linked to difficulties with phonological decoding (a symptom seen as less strongly embodied). Experiments 2-3 show that the embodiment of symptoms plays a causal role in promoting essentialist thinking. Experiment 2 shows that, when participants are provided evidence that the symptoms of dyslexia are embodied (i.e., they "show up" in a brain scan), people are more likely to consider dyslexia as heritable compared to when the same symptoms are diagnosed behaviorally (without any explicit evidence for the body). Finally, Experiment 3 shows that reasoning about the severity of dyslexia symptoms can be modulated by manipulating people's attitudes about the mind/body links, generally. These results show how public attitudes towards psychological disorders arise from the very principles that make the mind tick.

Project description:BACKGROUND AND OBJECTIVE:Intuition is an important part of human decision-making and can be explained by the dual-process theory where analytical and non-analytical reasoning processes continually interact. These processes can also be identified in physicians' diagnostic reasoning. The valuable role of intuition, including gut feelings, has been shown among general practitioners and nurses, but less is known about its role among hospital specialists. This study focused on the diagnostic reasoning of hospital specialists, how they value, experience and use intuition. DESIGN AND PARTICIPANTS:Twenty-eight hospital specialists in the Netherlands and Belgium participated in six focus groups. The discussions were recorded, transcribed verbatim and thematically coded. A circular and iterative analysis was applied until data saturation was achieved. RESULTS:Despite initial reservations regarding the term intuition, all participants agreed that intuition plays an important role in their diagnostic reasoning process. Many agreed that intuition could guide them, but were cautious not to be misguided. They were especially cautious since intuition does not have probative force, for example, in medicolegal situations. 'On-the-job experience' was regarded as a precondition to relying on intuition. Some participants viewed intuition as non-rational and invalid. All participants said that intuitive hunches must be followed by analytical reasoning. Cultural differences were not found. Both the doctor as a person and his/her specialty were seen as important determinants for using intuition. CONCLUSIONS:Hospital specialists use intuitive elements in their diagnostic reasoning, in line with general human decision-making models. Nevertheless, they appear to disagree more on its role and value than previous research has shown among general practitioners. A better understanding of how to take advantage of intuition, while avoiding pitfalls, and how to develop 'skilled' intuition may improve the quality of hospital specialists' diagnostic reasoning.
