The Managing Partner Did the Maths, Then Said No Anyway

A practice manager at a law firm told me, matter-of-factly, that she spends roughly half her working time searching. Not billing. Not managing her team. Searching. Documents, precedents, correspondence, buried somewhere inside systems the firm already owned. She said it the way you'd report the weather. It wasn't a complaint. It was just the shape of her week. The managing partner was standing with us and he didn't flinch. That was their normal, it seemed.

The firm could have fixed it. A solution I built, one that provides semantic search across the firm's own matter documents, would have let her find, in seconds, what was taking her hours: the right precedent, the right correspondence, the right version of the right document. The managing partner said no. Too expensive, he said, eyeing the monthly fee.

Let's break down what "too expensive" actually meant in this particular case.

His practice manager was losing roughly four hours a day to searching. There are roughly twenty working days in a month. The proposal was priced as a monthly subscription equivalent to about four hours of her time. The solution would have found her what she needed in minutes instead of hours.

He chose to go on paying her to work those four hours, every working day of the month, rather than pay for the solution. Run the maths and he chose a bill twenty times the size of the one he rejected, and got nothing for the difference except the comfort of having said no to something new. That failure was a valuable lesson to me.

Document chaos never shows up on a P&L as its own line. It gets absorbed into salaries, into the extra hour someone stays late, into a practice manager who has quietly stopped expecting her week to look any different. Nobody measures it because nobody is ever asked to.

Insight: this wasn't a decision about price. Managing partners run profitable businesses. They can do arithmetic; nobody makes partner without the ability to weigh a cost against a benefit. Which makes the refusal genuinely strange. A numerate, rational person looked at a return that would embarrass most investment committees and turned it down anyway. Why?

Why Doesn't a Stronger Business Case Change a Lawyer's Mind?

I connected with Dr Larry Richard, who has spent three decades studying how lawyers think. He has gathered and analysed personality data on thousands of lawyers using the Caliper Profile.

On an ILTA panel in August 2026, he offered the first-order explanation for exactly this pattern. "The legal profession as a substantive practice is based on the idea of precedent," he said. "... Anyone who's been in law practice for 10 years or more has had it burned into their brain that precedent, tradition, following the way things have always been done, is what we do. And when we're presented with a brand new opportunity, hey, try this new technology, their lawyer brain immediately goes, what are you talking about?"

That reflex explains why the managing partner's default setting was resistance. It doesn't explain why the resistance survived contact with the numbers, which is a different and harder question, one I've written about elsewhere in relation to what the word "unprecedented" does to a legal buyer. The more useful diagnosis here sits one layer below precedent-thinking, in the mechanics of how a persuasion attempt actually lands on a lawyer's brain.

Dr Richard has catalogued that mechanism in detail, using, of all things, timesheets. In a piece on his blog titled "Why You Should Never Try to Persuade Lawyers," which he walked me through on a call we had in September, he lays out four separate barriers a lawyer's brain throws up against being persuaded of anything, however sound the case. What makes his example useful here is that it is structurally identical to a sales pitch (my semantic search pitch, from above): a proposal to change a method of working, framed as improvement, but which lands as an accusation.

The first barrier is adversarial training. Lawyers are trained to oppose first and ask questions later. "Their first thought is, oppose you and tell you all the reasons why you're wrong, even if it's in their interest not to do so," Richard told me. Put a return-on-investment case in front of a managing partner and his first move isn't to weigh it. It's to find the cracks. The subscription price wasn't the real objection. It was simply the first defensible foothold that presented itself.

The second is high autonomy. "Even if turning in timesheets will make me more money," Richard says, describing the same reflex in a different context, "my reaction is, oh no, who are you to tell me what to do." A pitch for new software, however well argued, is still someone from outside telling a lawyer how to run her firm. Even a change that hands her money back arrives, to a high-autonomy brain, as an instruction. Instructions get resisted on principle, independent of their content.

The third is high scepticism. "Why are you asking me? Why didn't you ask my partner in the other office? You got something against me?" is how Richard describes the motive-hunting that follows. A managing partner primed to distrust the messenger doesn't evaluate the evidence on its merits. He looks for what's really going on. Vendors have an obvious motive to oversell, so even a genuinely strong case gets discounted for the fact that someone is trying to sell it.

The fourth barrier is the one most likely to have done the real damage here, and it has nothing to do with software. Richard describes it as a request that gets heard as a verdict: "What you hear is, whatever you're doing now regarding timesheets, you're deficient." A pitch to fix how the firm handles documents carries the same structure, whatever words were actually used to raise it. A low-resilience listener doesn't process "our systems need an upgrade" as a neutral observation. He processes it as a verdict on how he has run the firm. The pitch that followed wasn't an opportunity. It was evidence of a failure he now had to fix or defend.

In short, four reflexes fire before anyone reads the business case:

• Adversarial training: oppose first, weigh the evidence later
• High autonomy: outside advice arrives as an instruction, not an option
• High scepticism: the messenger's motive gets questioned before the message
• Low resilience: a pitch to improve something lands as a verdict on the person who built it

How Do You Actually Get a Lawyer to Say Yes?

Richard's own summary of the stack is blunt: "you've got four barriers, any one of which are game ending." And pushing past a no doesn't leave things where they started. "Not only have you failed in your persuasion effort," he says, "but now the person you aimed your efforts at has dug their heels in." A second attempt at the same ROI case, delivered louder or with a better spreadsheet, does not undo the refusal. It reinforces it.

This is why a better business case never stood a chance. The objection sounded like it was about price because price is the socially acceptable place to park a refusal that is actually about autonomy, scepticism and a bruised sense of competence, none of which a managing partner is going to say out loud in front of his own practice manager. Sharper arithmetic doesn't touch any of the four barriers. It only gets rejected more precisely.

Anyone selling anything into a law firm, myself included, runs the risk of making the same mistake: leading with the case and hoping the numbers do the persuading. The numbers were never the obstacle. Four reflexes were, all firing before the spreadsheet was even open. A pitch built by someone who believes the return-on-investment slide is the hard part will lose to those four reflexes every time. Design for the barriers, or accept that the person on the other side of the table will keep paying twenty times more to stay exactly where he is.

I know for a fact that the practice manager at that firm is still being paid to spend four hours a day searching for the right document. It's the same admin tax I wrote about in why UK legal professionals are trapped by admin, not the law, and the same resistance pattern behind the seven traits that explain why lawyers resist the tools built to help them.

Frequently asked questions

Why do lawyers reject a business case even when the numbers clearly work?

Because the numbers were never what they were reacting to. Dr Larry Richard's research identifies four reflexes that fire before a lawyer evaluates the evidence: adversarial training (oppose first), high autonomy (outside advice reads as an instruction), high scepticism (the messenger's motive gets questioned), and low resilience (a pitch to fix something lands as a verdict on the person). A stronger business case doesn't touch any of the four.

What is the real ROI when a law firm turns down new technology to save money?

In the case above, the firm's practice manager was losing roughly four hours a day, or around eighty hours a month, to manual searching. The technology that would have fixed it was priced at roughly four hours of her time a month. The managing partner rejected the smaller bill and kept paying the larger one, twenty times over, indefinitely.

What are Dr Larry Richard's four barriers to persuading a lawyer?

• Adversarial training: trained to oppose first, evaluate second
• High autonomy: instructions from outside get resisted on principle
• High scepticism: the pitch gets discounted for the fact that someone is selling it
• Low resilience: a fix reads as a verdict on the person who needed it

Isn't pointing out these barriers just another attempt to persuade lawyers?

Fair challenge, and it's not lost on me. This piece isn't aimed at talking a sceptical reader out of scepticism, which is barrier three, and it would fail for the same reason the original pitch did. It's aimed at the person doing the pitching. If you're the managing partner reading this, the useful move isn't to trust the article. It's to notice which of the four barriers your own reaction to it just activated.
