underestimator
One who discounts
An underestimator is someone who consistently judges things to be smaller, less important, or less capable than they actually are.
The term applies to people who habitually lowball costs, timelines, or the abilities of others—or themselves.
He's a chronic underestimator of how long projects take.
In statistics and forecasting, an underestimator may refer to a model or method that systematically produces values below the true measure.
