Telling people the real cost up front makes them stay

What this entitles us to say
A meta-analysis of 40 studies finding that realistic job previews — telling candidates the unflattering truth about a role before they accept it — are related to lower voluntary turnover and higher performance, at the cost of small decreases in job satisfaction.
What it found
40 studies, 26 of them published, on realistic job previews — giving candidates an accurate rather than flattering picture of a role. Previews were related to:
- Lower voluntary turnover, and lower turnover overall - Higher job performance (12 studies used performance as the outcome) - Lower, more accurate initial expectations - Higher attrition during recruitment — some candidates self-select out, which is the mechanism working - Small decreases in job satisfaction
Effectiveness varied with the timing and medium of the preview.
Why it matters here
The book's principle for this trait is commitment means counting the cost and agreeing to pay the price. This is the closest thing to a direct test of that sentence in the organizational literature, and it comes out the way the book says it should.
The mechanism is worth teaching in full, because it looks like a loss and is not. Honest previews cause more people to walk away at the point of decision, and fewer to walk away afterwards. A leader who undersells the difficulty of a project gets easier agreement and worse follow-through. A leader who states the real price gets fewer volunteers and better ones.
Note the honest cost: people who were told the truth report slightly lower satisfaction. They know what they took on. That is the trade, and hiding it would be the opposite of the trait.
This is also where Commitment touches Honesty — the trait works by telling people something they would rather not hear at the moment it is least convenient.
The limits
A 1998 meta-analysis of a recruitment practice, not of leadership character — the transfer to a leader asking for commitment on a project is ours, by analogy, and the analogy should be stated when it is used. Effects are moderated by the timing and medium of the preview and by whether the study was laboratory or field. The small decrease in job satisfaction is a real cost and must travel with the finding. Verified to abstract level.
What we do not say
that this proves the same for any commitment a leader asks for. It is recruitment research, and applying it to project commitment is an analogy — a good one, but ours, and it should be labeled as such rather than presented as a finding.
