Among some gifted education researchers, advocates, and practitioners, it is sometimes believed that there is a larger number of gifted people in the general population than would be predicted from a normal distribution (e.g., Gallagher, 2008; N. M. Robinson, Zigler, & Gallagher, 2000; Silverman, 1995, 2009), a belief that we termed the “overabundance hypothesis.” We tested this hypothesis by searching public datasets and the published literature for large representative datasets, 10 of which… Expand

I appreciate the opportunity to respond to the article by Warne, Godwin, and Smith (2013) on the question of whether there are more gifted people than would be expected in a Gaussian normalExpand
The Quantitative Implications of Definitions of Giftedness
Educational psychology is replete with verbal or qualitative definitions through which students can be considered members of categories, such as learning disabled, autistic, or gifted. TheseExpand
Five Reasons to Put the g Back Into Giftedness
Human intelligence (also called general intelligence, g, or Spearman’s g) is a highly useful psychological construct. Yet, since the middle of the 20th century, gifted education researchers have beenExpand
An Evaluation (and Vindication?) of Lewis Terman: What the Father of Gifted Education Can Teach the 21st Century
Lewis Terman is widely seen as the “father of gifted education,” yet his work is controversial. Terman’s “mixed legacy” includes the pioneering work in the creation of intelligence tests, the firstExpand
Do the Mega and Titan Tests Yield Accurate Results? An Investigation into Two Experimental Intelligence Tests
The Mega and Titan Tests were designed by Ronald K. Hoeflin to make fine distinctions in the intellectual stratosphere. The Mega Test purported to measure above-average adult IQ up to and includingExpand


Does the Normal Curve Accurately Model the Distribution of Intelligence
Like many human characteristics, intelligence is theorized to be normally distributed. However, a vocal minority of researchers and practitioners who study individuals with high intelligence haveExpand
Accountability for Gifted Students.
The call for a differentiated curriculum or program for gifted students raises the issues of how such changes should be made and how they should be assessed. Mr. Gallagher proffers some suggestions.Expand
Studying Intellectual Outliers
By studying samples of intellectual outliers across 30 years, researchers can leverage right-tail data (i.e., samples at or above the 95th percentile on tests of ability) to uncover missing pieces toExpand
Is Intelligence Distributed Normally
Frequency distributions obtained on applying intelligence tests to large samples of the school population are analysed, and compared with those given by the formulae for the commoner types ofExpand

Using two population-wide surveys of general intelligence in 11-year-olds in Scotland, it was shown that there were substantial departures from normality in the distribution, with less variability in the higher range than in the lower, and sex differences in variability did not appear to account for sex Differences in high-level achievement.

The Flynn effect puzzle: A 30-year examination from the right tail of the ability distribution provides some missing pieces
Abstract The Flynn effect is the rise in IQ scores across the last eighty or more years documented in the general distribution of both industrialized and developing nations primarily on tests thatExpand
Do Highly Gifted Students Really Have Problems?
This study addresses the question whether highly gifted students have particular school-related problems. To answer this question, 4 categories of gifted students are compared, consisting ofExpand

This paper argues that, provided samples are sufficiently large and complete, frequency-curves obtained exhibit small but significant deviations from strict normality, and, for most practical purposes, resulting distributions can be treated as approximately normal. Expand
The Measurement of Giftedness
