Data watch: Mentorship statistics frequently exhibit selection bias in organizations where participation is entirely voluntary. High performers who proactively seek out mentors are inherently more likely to earn promotions and exhibit longer organizational tenure regardless of pairing. To isolate true programmatic impact, modern benchmarking focuses on randomized cohort rollouts and controlled pilot initiatives within large enterprise divisions.
