Evidence labels
Different methods answer different questions
Observed / secret shopper
Researchers actually called, emailed, or submitted a form to a law firm and recorded what happened.
Survey-reported
Lawyers or consumers reported their own behavior, technology use, or preferences.
Observational association
A dataset shows that two things occur together without proving one caused the other.
Secondary source-tracing
A researcher reviews where a published benchmark originated. Useful for provenance, not a substitute for original testing.
Commercial interests
Commercial research is disclosed, not automatically rejected
Several of the strongest available legal-intake datasets are produced by companies that sell legal marketing, legal technology, directories, or intake services. CallShift identifies that relationship and avoids interpreting the findings beyond the published method.
What CallShift excludes
Repeated claims do not become benchmarks without a traceable source
- Generic “average law firm conversion rate” claims with no denominator
- The widely repeated “21x more likely to qualify within five minutes” claim when presented as law-firm-specific without a law-firm study
- After-hours percentages derived from studies conducted during normal business hours
- Marketing-vendor case-study results presented as if they describe the full legal industry
- Revenue-loss estimates built on multiple unverified assumptions
Correction policy
Material changes remain visible
If a source is updated, corrected, or contradicted by its own supporting materials, CallShift will revise the page and preserve a plain-language note explaining the change when material.
