Stealing thunder in courtroom persuasion

A lawyer knows something bad about a client. Should the lawyer wait for the other side to announce it, or bring it up first? Stealing thunder means volunteering that damaging information before the opponent reveals it. The fact stays the same, but the lawyer may gain control over how the jury first understands it.

Picture a public figure admitting a youthful mistake before an opponent turns it into a scandal. The admission can sound candid and let the person put the event in context. When the opponent brings it up later, the response may be: we already knew that. That's the same basic idea the lawyer is using here.

But why reveal a weakness that the opposition won't use? The first paragraph gives us that practical limit. If the opponent doesn't know about the information, or wouldn't exploit it anyway, volunteering it has no point. Many lawyers favor getting ahead of a damaging revelation when that revelation is likely to happen. Keep the expected attack in view; otherwise, we're just supplying our own bad news.

The second paragraph gives us support for the strategy, with an important research limit. No empirical research has directly tested it in actual trials. Simulated trials nevertheless suggest that it works in a reasonably broad range of situations. Those are useful findings, but a simulated trial is not an actual one.

Then come several psychological explanations. First, admitting something against your own interests can make you look credible. Someone who acknowledges a weakness may seem more trustworthy than someone who presents only flattering information. Greater credibility can make the lawyer more persuasive; the damaging admission doesn't have to become a good fact for that benefit to occur.

Second, the warning lets jurors prepare. If they know the opposition will try to persuade them using this information, they may begin forming counterarguments. The lawyer has previewed the attack, so the jury is less vulnerable to its force when it arrives.

Third, the information can lose some of its novelty. The author compares a persuasive message with a scarce commodity: something may be valued less when it is no longer scarce. If both lawyers discuss the same fact, the opponent's revelation becomes old news. That can reduce its weight, unless the evidence is so consequential that repetition cannot take much of its power away.

The final paragraph returns to framing. A lawyer can explain the negative information in favorable terms and downplay its significance. Jurors are eager to reach a firm view of the case, so that early interpretation can guide how they evaluate later evidence. This is more than making a good first impression; the first impression may become the lens through which they understand what follows.

That also explains the danger. Some facts are extremely difficult to frame positively. Compare admitting a minor youthful mistake with admitting conduct that caused grave harm: the second admission may be much harder to soften. If it creates a strongly negative first impression, the same tendency to settle on an early view now works against the client. Later information gets filtered through that damaging impression.

So the overall reaction is favorable, with limits. Stealing thunder has experimental support and several plausible psychological explanations. It can reduce the damage from an expected attack, but it isn't a way to make every bad fact harmless.
