The Overestimation Of Those Who Are Marginalised

A recent YouGov study revealed a widespread phenomenon: people significantly misestimate the size of small subgroups within the population. Respondents believed that 30% of Americans are gay or lesbian (the actual number is around 3%), 27% are Muslim (actual: 1%), and 41% are Black (actual: 12%). Conversely, they underestimated the prevalence of larger groups believing, for instance, that only 58% of Americans are Christian (actual: 70%). Even neutral traits, such as being left-handed, were believed to be more common than they are.

The researchers explain these errors through a cognitive process known as uncertainty-based rescaling. When people are unsure, they tend to estimate toward the midpoint, usually around 50% which inflates minority group figures and compresses the size of majority groups. Strikingly, even individuals within the minority groups often misjudged the size of their own communities. Furthermore, correcting these perceptions rarely shifts people's attitudes about social or political issues, showing how resistant these misperceptions are to change (Orth, 2022).

Misperceptions and Leadership Blind Spots

This matters for leaders because perception shapes action. Leaders who unknowingly overestimate the representation of marginalised groups may believe diversity and inclusion efforts are no longer necessary, or worse, overdone. This can create a dangerous disconnect between policy and lived experience. Underestimating the scale or needs of other groups, such as disabled employees, religious minorities, or those without a college degree can result in exclusion by neglect.

Misperceptions can also drive tokenism, where visibility of a few is mistaken for broad inclusion. Similarly, leaders may overlook dominant group dynamics like the influence of class, gender, or education in shaping organisational norms and biases.

Practical Strategies for Leaders and Organisations

• Use actual data, not assumptions
  Conduct regular, confidential demographic audits and engagement surveys. Know who is in your workforce and how they experience the organisation.

• Challenge middle-point bias in decisions
  When making people-related decisions (e.g. promotion, policy development, representation on panels), explore whether assumptions are guiding actions. Ask, Who are we designing this for? Who is being overlooked?

• Build data literacy into leadership development
  Train leaders to recognise how perception errors and cognitive biases affect organisational thinking. Equip them to work with evidence, not instinct.

• Reinforce that visibility ≠ representation
  Just because a group is vocal or visible doesn’t mean it is adequately represented or supported. Avoid letting anecdotal experiences stand in for systemic understanding.

• Design with nuance
  Go beyond majority-minority thinking. Recognise the complexity of identity and experience, and resist simplifying people into binary categories.
  
  

Reclaiming Reality for Inclusive Performance

When we misjudge who is in the room, we risk misdirecting resources, designing poor strategies, and reinforcing inequality. Leadership requires more than good intentions, it demands clarity. The YouGov findings are a reminder that our brains are wired for bias, but our organisations don’t have to be. By anchoring leadership in real data, critical thinking, and inclusive design, we can bridge the gap between perception and performance, and ensure no one is left out because they were simply miscounted.
