Software companies publish studies about their own software. They can be useful, and they have limits that a reader should know.
This article reports three Clio findings. It says who ran each one and does not generalize them to other tools or to our work.
A study of mental effort
Clio ran a study with the firm Neuro-Insight. The vendor funded it, and it has not been peer reviewed.
Clio, Legal Trends Report 2025, 2025 (https://www.prnewswire.com/news-releases/the-science-behind-smarter-law-clios-2025-legal-trends-report-reveals-how-technology-is-rewiring-the-way-lawyers-work-302585725.html): Clio's study with Neuro-Insight involved 63 legal professionals, 48% of them lawyers. They did tasks of 2.5 to 5 minutes, first with Excel and PDF as a control and then with Clio.
Clio, Legal Trends Report 2025, 2025 (https://www.prnewswire.com/news-releases/the-science-behind-smarter-law-clios-2025-legal-trends-report-reveals-how-technology-is-rewiring-the-way-lawyers-work-302585725.html): in the same study, active mental effort fell by 72% when calculating billables and by 25% when creating new matters. Emotional strain fell by 16% during intake.
Limits of that study
The tasks were short and done in a controlled setting. The group was small. The comparison was between spreadsheets and PDF files and one software tool.
It says nothing about other tools, about longer real-world work or about what Kalla Connect builds.
Correlations reported by the vendor
Clio also reports differences between firms. These are correlations: firms that grow tend to adopt more tools, and that does not show that the tools caused the growth.
Clio, Highlights from the Legal Trends Report 2024, 2024 (https://www.clio.com/blog/highlights-from-2024-legal-trends-report/): firms using intake features were associated with 51% more leads and 52% more revenue, as reported by Clio.
Clio, Legal Trends Report 2025, full report, 2025 (https://www.clio.com/resources/legal-trends/read-online/): growing firms use automation twice as much as stable firms. This is also a correlation.
What we did not find
We did not find an independent, peer-reviewed study that measures the effect of automation on U.S. law firms. That does not mean there is no effect. It means we have nothing measured to report.
How to read a vendor study
- Who paid for it, and who ran it?
- How many people took part, and what did they do?
- Is it a comparison or a correlation?
- Does it say anything about the firm's own kind of work?
