In Simple Words

Imagine asking two people to predict how well their friends will solve a set of complex math puzzles. A math expert accurately judges which friends possess true mathematical talent, whereas someone who struggles with basic arithmetic cannot tell which of their friends is actually good at solving math problems.

Male referrers in Kolkata

Above-average puzzle scores
Score change 0.190 standard deviations per predicted puzzle
Below-average puzzle scores
Score change 0.025 standard deviations per predicted puzzle

Observed score groups. Changes per extra puzzle predicted solved. Low-score estimate uncertain, with weak instruments; no causal group or formal interaction claim.

Research question

Workers across different ability levels do not possess equal capability in estimating the cognitive job skills of their peers, resulting in unequal screening effectiveness across the workforce.

Participants

N = 505 male labor market participants (280 high-ability, 225 low-ability) in Kolkata, India.

Study Design

Heckman selection model regressing actual referral puzzle task scores on referrer pre-task predictions across high-ability vs low-ability participant subsamples.

Results

High-ability workers accurately predicted referral puzzle scores (coefficient = 0.190, p < 0.05), corresponding to an 0.8 standard deviation performance difference, whereas low-ability workers showed no statistically significant predictive accuracy (coefficient = 0.025, p > 0.10).

Takeaway

Audit referral recommendations based on referrer job performance before relying on referrer predictions, as low-performing employees lack the ability to accurately gauge peer capability.

Statistically significant

A label used when a result passes a chosen statistical threshold, often p < 0.05. It does not show how large or useful an effect is. A result that is not statistically significant does not prove there is no effect.

ExampleA study reports p = 0.03 against a 0.05 threshold. It passes that test, but the effect could still be too small to matter.

    Imagine trying to pick the best chess player out of a crowd. Only a master chess player has the expertise to accurately assess who among their acquaintances truly plays at an elite level, whereas a beginner cannot distinguish between a decent amateur and a grandmaster.

  • Low-Ability Foot-in-the-Door Effect →Labour & employment

    Giving lower-scoring job candidates short-term work exposure works like a physical foot in a closing door. Instead of getting permanently shut out by low written screening test scores, the temporary work placement allows candidates to demonstrate real-world work habits directly to employers, overriding initial negative paper credentials.

  • Self-Belief Updating and Directed Job Search →Labour & employment

    Skill assessment feedback acts like a mirror and a GPS navigation tool for a job hunter. By showing workers their exact strengths compared to others, it stops them from walking down dead-end paths and guides them directly toward job opportunities where their specific skills are valued.

    Imagine a nightclub with a strict dress code based on exam scores where high scorers enter easily without extra effort. For high-scoring individuals, additional work experience adds little value because employers already hire them based on test scores.
