Yes, you really should respond to that inane argument.

In any disagreement, it’s incredibly tempting to only respond to the arguments that you think are persuasive and simply dismiss those that you find absurd. Unfortunately, as can be easily seen in any political debate, that often leaves both sides talking past each other – and never actually addressing the other side’s concerns. Unless and until you actually address the opposing arguments directly – even those you think are ridiculous – you are simply “preaching to the choir.” And while it is important to provide ammunition to those who are on your side, ideally, you would like to persuade those who are on the fence or against you.

To highlight this issue, think about a political issue you feel strongly about. Now consider the opposing arguments on that issue. Do they actually address your concerns? Or do you feel they are missing the point entirely? Are you persuaded by arguments that don’t address your concerns?

This same dynamic surrounds practically every sensitive issue that people have a vested interest in. Consider vaccines, for example. Vaccine resisters believe that there are real and widespread risks of vaccines that outweigh the risks of childhood diseases. They fear that vaccines will cause permanent injuries and changes to their child. Vaccine advocates emphasize the seriousness of those childhood diseases and our social responsibility in protecting vulnerable populations who cannot be vaccinated. The advocates’ approach is typically to scoff at anti-vaxxers or to focus on educating them. However, their arguments are rarely persuasive to those who oppose vaccines, because they dismiss the fundamental force driving their position – fear of causing harm to their child – instead of addressing it.

In fact, studies designed to examine what arguments actually influence anti-vaxxers’ thoughts about vaccines have found that parents’ vivid and detailed descriptions of their child actually getting those diseases (measles, whooping cough, etc.) are most effective. This is likely because those personal accounts speak to the fear in vaccine resisters – and elevate their level of fear concerning childhood diseases to a point that balances out the scales a bit more.

Every time you go to trial, you are introducing new topics to jurors and asking them to become invested in the issues – which they do. But to create the greatest chance that they will become invested in your position, you can’t simply hope they think like you and will be persuaded by the same arguments you are persuaded by. You should consider that some jurors may have a different perspective – one that you would like to change. So next time you don’t want to bother addressing an opposing argument because “no one will ever believe that,” remind yourself that someone will. And he/she may be on your jury.
