Intelligent Bias
A bias that paradoxically results from high intelligence or critical thinking skills when they are applied selectively. For example, an intelligent person may be better at rationalising their existing beliefs (motivated reasoning), finding flaws in opposing arguments while ignoring weaknesses in their own, or using their cognitive abilities to manipulate others. Intelligent bias is dangerous because it wears the mask of rationality.
Intelligent Bias Example: “He was brilliant at dissecting the flaws in her evidence, but never turned that same scrutiny on his own sources. Intelligent bias: smart rationalisation, not smart reasoning.”

Intelligence Biases
The collection of biases that distort how we perceive, measure, and value intelligence: the Flynn effect denial (ignoring generational gains), the bias towards academic intelligence, the naturalisation of IQ differences, the bias against neurodiversity, and the simplistic use of single scores. These biases harm education, employment, and social policy by promoting a narrow, often discriminatory view of human capability.
Intelligence Biases Example: “Her research on intelligence biases showed that schools that track students by IQ scores systematically underestimate late bloomers and children from non‑dominant cultures.”

Intelligence Bias
A bias that occurs when one overvalues or misdefines intelligence in a way that distorts judgment. This can mean assuming that intelligent people are more trustworthy, more moral, or better leaders (the halo effect). It can also mean conflating intelligence with specific skills (e.g., mathematical ability) while ignoring other forms of intelligence (emotional, social, practical). Intelligence bias leads to elitism and poor decision‑making, especially in hiring and education.
Intelligence Bias Example: “The manager only promoted graduates of elite universities, confusing high test scores with leadership ability—intelligence bias at work.”

IQ Biases
A set of interrelated biases that cluster around IQ testing: cultural bias in test design, environmental bias (ignoring nutrition and schooling), scoring bias (assuming equal intervals across the scale), heritability bias (overstating genetic contribution), and reification bias (treating a constructed score as a real thing). IQ biases reinforce social hierarchies by making contingent outcomes seem natural and inevitable.
IQ Biases Example: “The textbook’s chapter on intelligence suffered from multiple IQ biases: it used old, culturally loaded questions and concluded that group differences were genetic.”
IQ Bias
A specific bias involving the use or interpretation of IQ scores. It includes the assumptions that IQ measures innate intelligence, that it is culturally neutral, and that it predicts success across all domains. IQ bias ignores the Flynn effect, the role of education and socioeconomic status, and the multiple dimensions of intelligence. It also includes the tendency to treat IQ as a fixed, hereditary trait, leading to deterministic and often discriminatory conclusions.
Dynamic-Complex Bias
A bias that is both dynamic (shifting with context or time) and complex (arising from multiple interacting factors). For example, political polarisation bias fluctuates with news cycles, social media algorithms, and group dynamics; it involves confirmation bias, identity protection, selective exposure, and emotional contagion. Dynamic‑complex biases are the hardest to detect and counteract because their drivers change and interact.
Dynamic-Complex Bias Example: “The dynamic‑complex bias of her vaccine hesitancy shifted with each new headline: fear of needles, distrust of pharma, a friend’s anecdote, then reassurance from a trusted doctor. It wasn’t one bias; it was a storm.”

Simple-Static Bias
A bias that is both simple in its mechanism and static in its persistence. It operates through a straightforward cognitive shortcut and remains relatively unchanged over time. For example, the anchoring effect (relying too heavily on the first piece of information) is simple (a single mental heuristic) and static (it works similarly across situations). Simple‑static biases are often the easiest to study in controlled experiments.
Simple-Static Bias Example: “The simple‑static bias of ‘price anchoring’ made him judge the sale price as cheap only because he’d seen the inflated original first. Same bias, same effect, every time.”
