Proximity Bias
Proximity bias is the documented tendency for managers and decision-makers to unconsciously favor employees they physically see over those who are remote — assigning them higher performance ratings, more visible projects, and stronger advocacy in promotion decisions. The mechanism runs on availability heuristics: people who are physically present are mentally available, which managers implicitly translate into impressions of engagement, commitment, and trustworthiness. Bloom's Ctrip trial produced the clearest causal evidence: remote workers outperformed in-office peers by 13% yet were promoted at half the rate, demonstrating that proximity advantage operates independently of actual output.
SEE THE PRACTICE
Turn a thought this research explains into one clear move.
THE THOUGHT
“The in-office people get promoted — not the remote ones”
YOUR RECORDED RESPONSE
“My output is real whether it was made in an office or at a desk. I don't need an audience to make it valid.”
ONE PRIVATE MOVE
Open your completed work from the last month. Write down three deliverables by title and date. Read the list back to yourself. None of these became unfinished because they were made remotely.
How it sounds in your head
The inner script: 'I'm doing great work — my numbers are strong — so I must be on track for the next promotion.' Proximity bias rewrites the script: your manager's mental model of who's 'promotable' is built from daily hallway moments, lunch reads, and casual project updates — all of which you're absent from. Strong output is necessary but not sufficient when visibility is the bottleneck.

01 Why does proximity bias persist even when remote workers have objectively better performance metrics?
Proximity bias is a cognitive phenomenon, not a policy. It operates through the availability heuristic: people who are physically present become mentally salient, and managers implicitly assign them higher scores on subjective dimensions like 'commitment' and 'team player' — dimensions that dominate promotion decisions even when objective performance data exists. source ↗
