Claim: Felps, Mitchell, and Byington demonstrated experimentally that a single negative team member reduces team performance by 30-40%.
BLUF: Confirmed. Felps, Mitchell, and Byington (2006) studied 40 groups with planted actors displaying toxic behaviors (jerk, slacker, pessimist) and found a single bad apple reduces team performance by 30-40%. This finding has been widely cited and reported.
Probability: Almost certain (95-99%) | Confidence: High
