From Peter Bregman of the Havard Business Review Blog Network titled Arguing Is Pointless …

“Think about it. You and someone have an opposing view and you argue. You pretend to listen to what she’s saying but what you’re really doing is thinking about the weakness in her argument so you can disprove it. Or perhaps, if she’s debunked a previous point, you’re thinking of new counter-arguments. Or, maybe, you’ve made it personal: it’s not just her argument that’s the problem. It’s her. And everyone who agrees with her.

In some rare cases, you might think the argument has merit. What then? Do you change your mind? Probably not. Instead, you make a mental note that you need to investigate the issue more to uncover the right argument to prove the person wrong.”
