In Simple Words
Imagine a crowded factory floor where machines periodically stall or run out of cloth, but hesitant operators remain silent and wait for help. Targeted soft skills training acts like turning up the volume dial on an operator's willingness to speak up, enabling them to communicate immediately with peers and supervisors to resolve assembly bottlenecks and maintain production speed.
Women surveyed in the Bengaluru trial
- No training on control lines
- Comparison group
- P.A.C.E. soft skills training
- Estimated higher extraversion
At program completion: estimated increase of 0.164 SD in outgoing behavior. Uncertain after accounting for multiple tests (q = 0.108); no proof it caused output gains.

Firms need to identify the specific psychological mechanisms through which soft skills training translates into workplace productivity improvements, rather than treating training as a black box.
Participants
N = 621 female garment workers (experimental survey sub-sample from 2,703 RCT participants) in Bengaluru, India.
Study Design
Two-stage randomized controlled trial (RCT) combined with causal mediation analysis using inverse probability weighting to decompose productivity treatment effects into non-cognitive trait mediators.
Results
Soft skills training increased worker extraversion by 0.164 standard deviations (p < 0.05), with mediation analysis establishing that gains in extraversion accounted for approximately 30 percent of the total 10.8 percentage point increase in workplace productivity.
Takeaway
Incorporate peer-interaction and assertive role-playing modules in frontline worker training programs to specifically target extraversion as a driver of operational bottleneck resolution.

- Percentage points
The difference between two percentages.
ExampleA rise from 40% to 50% is 10 percentage points. Relative to the starting value, that is a 25% increase.

A study that uses chance, like drawing lots, to decide who receives each option being compared. Researchers compare the groups’ outcomes to estimate the effect of those options.
ExampleA lottery assigns volunteers to a training programme or a comparison group. Researchers then compare their outcomes.
