Most of what we think we know about negotiation is based on intuition, anecdote, and the kind of practitioner wisdom that gets passed down through business school classrooms without anyone ever stopping to ask: is this actually true? Two recent conversations — one with a behavioral scientist who has spent decades applying psychology to persuasion, and another with a researcher using AI to analyze real negotiation conversations — offered something rarer and more valuable: evidence.
The findings are surprising, validating, and in some cases, a little humbling.
You're Probably Not as Curious as You Think
One of the most repeated pieces of advice in negotiation is to ask more questions. It turns out most people aren't taking that advice — and they don't even know it.
When researchers analyzed recorded negotiations, they found that the vast majority of what negotiators said was a statement, not a question. Open-ended questions were far rarer than anyone expected. What made the finding even more striking was what happened when those same negotiators were asked to estimate their own performance afterward: they believed they had been far more inquisitive than they actually were. The gap between perception and reality was enormous.
This isn’t just an interesting observation. Research consistently shows a strong connection between the number of open-ended questions a negotiator asks and the quality of the deal they walk away with. More questions, it seems, is simply better.
The implication is worth sitting with. Most of us believe we’re practicing the fundamentals. The evidence suggests we're not and we're not even aware of the gap.
Admit the Flaw Before They Do
One of the most counterintuitive and practically useful insights from behavioral science involves what researchers call the Stolen Thunder effect. The basic premise: when someone with a weakness in their argument admits that flaw before the other side can expose it, they come across as significantly more trustworthy and everything else they say becomes more believable as a result.
The application for negotiators is direct. Walking into any high-stakes conversation pretending your position is airtight when it isn’t doesn’t just fail to help, it actively undermines credibility. The other party is likely already aware of the weakness, or will be soon. Getting ahead of it turns a liability into a trust-building moment.
The key is choosing the right flaw to admit. The most effective communicators find weaknesses that carry a mirror strength — the premium price that signals quality, the slower process that signals care. It's not about humble-bragging or manufacturing a fake vulnerability. It's about being honest in a way that reframes the limitation as evidence of something worth believing in.
Make It Concrete, Make It Precise
Two other insights from behavioral science reinforce each other in ways that have immediate practical value.
The first involves specificity. When people hear precise claims rather than round numbers, they tend to perceive them as more accurate and more credible. Over time, we've all learned to associate round numbers with guesswork and specific numbers with genuine knowledge. The precision itself signals legitimacy — which means that rounding your data down to a clean number for the sake of simplicity may actually be costing you credibility.
The second involves concrete language. People remember vivid, visualizable words far better than abstract ones. Claims about quality, trustworthiness, or value tend to fade quickly because they’re intangible. Specific, sensory images stick. Apple didn’t sell megabytes of storage, they sold a thousand songs in your pocket. The lesson isn't to oversimplify; it's to translate what you know into language that people can actually picture. If the other party can't see it, they probably won't remember it.
The Emotional Intelligence You're Missing
One more insight deserves attention — this one about internal negotiation rather than external. Research on decision-making suggests that people who pause to identify multiple emotions they're feeling before making a decision tend to be more satisfied with those decisions afterward than people who stop at the first, most obvious feeling.
The parallel to negotiation is exact. Just as skilled negotiators ask more questions of the other party rather than assuming they already know the answers, the best decision-makers ask more questions of themselves. The first emotion that surfaces — frustration, anxiety, excitement — is rarely the whole story. Sitting with the question of what else is present tends to produce better, more considered outcomes.
The through-line across all of these insights is the same: the gap between what we think we're doing and what we're actually doing is wider than most of us want to believe. That's not a reason for discouragement. It's a reason for curiosity — and for treating every conversation as an opportunity to close the gap.
