Inequality, by most measures, is high and getting worse. Governments, economists and HR departments treat this as a given – and respond on the assumption that the people affected know it, feel it and are ready to act on it. Our research suggests that assumption is wrong. In our study tracking working adults, we found that people registered social differences in fewer than one in five moments over the course of six days even though the cues are everywhere: housing, job titles, accents and the schools people attended or send their children to.

Whether people notice inequality depends not just on the structures around them but on who they are, where they are and what they are doing at that moment. People don't observe inequality objectively – they encounter it selectively, shaped by their identity, psychology and immediate context. Most country-level policy and many company-level leadership interventions rest on the assumption that inequality is front of mind. Our data challenges that.

Noticing inequality: a momentary experience

To understand how people experience inequality, we used the Experience Sampling Method to collect real-time data from 301 working adults in Singapore over six days. Participants were prompted four times a day at random, contributing to 6,150 observations of whether they noticed social class differences, compared themselves to others and perceived those differences as fair or unfair.

The findings surprised us. Inequality surfaces and then fades; people are not constantly tracking inequality. Our research finds that they move through daily life with many competing demands on their attention and inequality is just one signal among many – noticed in moments rather than continuously.

In this context, people are less likely to perceive structural barriers to opportunity and upward mobility. This can weaken support for interventions aimed at addressing inequality, particularly in societies where meritocracy is strongly valued.

Who notices?

The question, then, is who notices inequality. We found three factors that consistently predict who is more likely to notice inequality:

• People who frequently compare themselves to others were more likely to notice social class differences. 
• Those who see status hierarchies as natural and meaningful were more attuned to these cues, paying closer attention to differences in rank and position. 
• Individuals with stronger fear-based attitudes towards migrant workers were more likely to register class differences in their environment.

These are psychological filters, not structural features of inequality itself. The same workplace or policy can land very differently depending on who encounters it. Inequality may be visible to everyone, but it is not equally noticed.

A common assumption is that once people notice inequality, they will naturally compare themselves to others and feel its sting. But inequality only becomes meaningful when people internalise it as something that reflects their position. Our findings show that people who tend to compare themselves to others were more likely to make that shift, as compared to those who place greater importance on material success. 

Comparison shapes perception of fairness

Even when people compare themselves to others, they may not necessarily draw the same conclusions. Our findings show that individuals with more egalitarian values were significantly more likely to judge inequality as unfair, whereas those who were more comfortable with hierarchy and more accepting of unequal status differences are less likely to register it as unjust.

But our most striking finding was this: Even people who are generally comfortable with hierarchy were more likely to judge inequality as unfair when they compared themselves to others more than usual. It wasn’t only about stable beliefs or values. The act of comparison itself changed how people interpreted inequality, from mere background noise to something personal. 

Comparison does not just make inequality more visible but changes the moral lens through which people see it. From this perspective, what might otherwise feel normal could suddenly feel unfair.

What this means for leaders

Inequality is not just a structural condition. It is a psychological process that works in stages: First people notice it, then they compare themselves to others, then they decide whether it is fair. At each step, individuals diverge – shaped by who they are, not just the actual extent of the gap.

For leaders, the challenge is not only managing inequality itself but managing the moments it registers, especially when making promotion decisions, during compensation discussions and when public recognition is given.

This is where transparency matters. When people become aware of differences in pay, promotion or recognition, they look for explanations. In the absence of clear principles, those differences are more likely to feel arbitrary or unfair. Instead of assuming fairness is self-evident, leaders need to make the principles behind decisions visible: how promotions are determined, how opportunities are allocated, and what standards guide recognition and reward. 

The goal is not simply to reduce inequality, but to ensure that where differences exist, they are understood to be legitimate and fair. People cannot respond to something they haven’t registered. But when they do register it, how they read it shapes trust, motivation and culture in ways that compound over time.
