A great deal is known and has been written about the difficulties that high IQ children can experience in the classroom when their special educational needs are not met. Evidence suggests that these difficulties can result in poor academic performance. This study is different from the research carried out in this field so far in that it expresses an hitherto unheard adult voice. It does so by examining the causes and the long-term effects of academic underachievement, as perceived by high IQ adults, on reflection. A mixed quantitative/qualitative methodological approach was used. 158 members of British Mensa, the High IQ Society, completed one semi-structured open ended questionnaire about their perceptions of the causes and long-term effects of their academic underachievement. A second questionnaire was completed by 50 of the previous sample who had revealed that they had reversed their underachievement in adulthood. This highlighted the differences between their educational experiences as children and as adults. It also revealed the impact that their delayed academic achievement had had on their life trajectory. Out of those 50 participants, ten took part in semi-structured one-to-one interviews which allowed for more in-depth enquiry. The conclusions of the study were that, if not nurtured, an innate ability such as a high IQ can become a disadvantage over time. It suggests that not catering for the special educational needs of high IQ children by not providing the mental stimulation they need is 'intellectual neglect'. Such neglect, like physical and emotional neglect, may affect mental well-being in adulthood. In the study sample, most of the participants' long-term economic and mental health had been negatively affected by their academic underachievement, even when it had been reversed in adulthood. This is an area which seems to have been little researched so far, perhaps because of the difficulty of locating high IQ underachieving adults. Yet, the issues highlighted by the research are of great importance not only to the individuals concerned but also to society. The desired outcomes of this study are that the dissemination of the results will raise awareness amongst educators and policy makers of the potential negative long-term effects of neglecting high IQ children's intellectual needs. It will also provide a platform for further research.

Research on highly intelligent individuals convicted for crime is relatively scarce. Many previous studies have found a link between low IQ and crime and seen higher IQ as aprotective factor for criminal activity. The current study questions whether it is really the case that high IQ would act as a protection factor and examines what motivates highly intelligent individuals to commit offenses. The study uses a qualitative method. A total of 10 semi-structured interviews were conducted with individuals (seven men, three women) who had at least 126 in IQ, and were convicted for one or more crimes. A thematic analysis with an inductive approach was performed, after which the theory of rational choice and the theory of social bonds were chosen to interpret the collected data. The results showed that all participants ruled out the option of giving up crime, either for the reward of the crime or because they considered the criminal act necessary. It also emerged that several of the participants had committed many more crimes than they had been convicted for. Exclusion of various kinds was another picture that was painted, as well as a feeling of leading during school time. A further discussion on the relationship between intelligence and crime is initiated and proposals for further research are given. / <p>2022-01-31</p>

The difficulty of distinguishing between genuine disorder and characteristics that can be attributed to high IQ increases the likelihood of diagnostic error by mental health practitioners. This mixed methods study explores the possibility of misdiagnosis of high IQ youth by mental health professionals. Participants were private practice mental health professionals who read case study vignettes illustrating high IQ youth exhibiting characteristics associated with their population. Participants then completed a survey and provided an assessment of the hypothetical client. In the study, 59% of participants were unable to recognize behavioral characteristics associated with high IQ youth unless suggested to them, and 95% of participants were unable to recognize emotional characteristics associated with high IQ youth unless suggested. The results of this study provide much-needed empirical exploration of the concern for misdiagnosis of high IQ youth and inform clinical practice and education.
