Our Responsibility to Defend the Truth

Science denialism has existed as long as science has existed. As a part of our social contract, we’re responsible for challenging the spread of misinformation and understanding, especially when it comes to science. If we open ourselves up to these difficult conversations, we can offer up a path into more logical reasoning and avoid a culture where science and truth are rejected.

Science Denialism is Dangerous

All science denialism relies on a flawed blueprint of cherry-picking evidence, trusting conspiracy theories, trusting fake experts, and relying on illogical reasoning. The internet has given denialism a chance to be amplified, which is especially dangerous because it confuses people and muddies the line between fact and falsehood. Science denialism hurts us in so many ways, from killing our planet by ignoring climate change to taking lives because people don’t trust vaccines and masks.

Technique Rebuttal

Content rebuttal is using facts to combat false claims. Technique rebuttal is challenging the logic of the argument. It may seem logical to defend the truth with the facts, but you can make more progress by talking about the core of people’s beliefs. If someone has already made the choice to deny the facts, presenting them with even more facts will not be effective. Instead, build trust by making them feel heard, then point out inconsistencies in their reasoning and use facts judiciously.
