The honest audit of that literature, including its weaknesses

What this entitles us to say
A review of eight reviews and meta-analyses, which reproduces the pattern — attitudinal effects moderate to strong, behavioral effects weak — and simultaneously judges the whole literature's conclusions "tentative" on methodological grounds.
What it found
Eight systematic reviews and meta-analyses of psychological contract breach, synthesized. The reported ranges divide cleanly:
- Attitudinal outcomes, moderate to strong. Organizational trust r = −0.36 to −0.53; job satisfaction r = −0.38 to −0.45; organizational commitment r = −0.32 to −0.38. - Behavioral outcomes, weak. In-role performance r = −0.07 to −0.20; organizational citizenship behavior r = −0.11 to −0.31.
Organizational tenure was the strongest moderator. On the field's health the authors are direct: there are no broadly accepted instruments for measuring the construct, the designs are overwhelmingly correlational and cross-sectional, the data are self-reported, and the reviews themselves score poorly for quality. Their conclusion is that findings about the impact of breach "remain tentative."
Why it matters here
Two jobs. First, it is where the published numbers come from — it is the only entry in this dossier verified to full text, so figures quoted in sales material should be sourced here and attributed as ranges across a literature, never as a single finding.
Second, it is the counterweight, and the same move the Honesty dossier makes with the integrity-testing argument. A buyer's advisor who knows this field knows it is contested. Raising it first is a far stronger position than being caught having left it out — and it is the fourth principle in practice: we cite, we do not claim expertise.
Note which side of the split is strong. Trust takes the largest hit of anything measured. The trait whose research base is weakest on productivity is strongest on precisely the thing CDL says it buys.
The limits
This entry is a caveat. Its specific limits: it reviews reviews rather than primary studies, so it inherits their flaws; the eight reviews scored only 4.5–6.5 out of 11 on the AMSTAR quality instrument; and the ranges below are pooled across reviews using different measures, so they describe a literature rather than a quantity.
What we do not say
Any of these figures as a settled quantity, a causal claim, or a promised return. The authors' own word for their conclusions is tentative; ours cannot be stronger than theirs.
