The idea that different opinions can make a group smarter has been tested. Some studies show that when people consider views they don't agree with, the group's guesses get better. However, other research using complex models found no improvement. This raises a big question: does disagreeing really help, or not?

To figure this out, three big experiments were done. Over 2, 800 adults from the US and UK took part. The findings were clear: disagreeing helps with tough questions, but it can mess up answers to easy ones. So, the difficulty of the question matters a lot.

Think about it. When a question is hard, hearing different views can bring in new ideas. This can lead to better answers. But for easy questions, too many views might just add confusion. So, it's not just about having different opinions. It's about knowing when they help and when they don't.

This is important for anyone trying to make a group smarter. They need to think about how hard the question is. Only then can they know if encouraging different views will help or not. It's not a one-size-fits-all situation. The key is to be smart about when to use this tool.

In the end, the power of disagreeing views is real, but it's not simple. It depends on the situation. So, next time you're in a group, think about the question. Is it tough or easy? That might decide if different views will help or not.
