What I like about sceptics is that in good science you need critics that make you think: 'Crumbs, have I made a mistake here?' If you don't have that continuously, you really are up the creek. The good sceptics have done a good service, but some of the mad ones I think have not done anyone any favours.

Summary

This quote emphasizes the importance of skeptics in the scientific process. It highlights how legitimate critics and skepticism can push scientists to question their own work, helping them uncover any errors or oversights. Such critical thinking is essential in avoiding personal biases and ensuring the integrity of scientific research. However, the quote does acknowledge that while constructive skepticism can be valuable, unwarranted and extreme skepticism can be detrimental and unhelpful to the scientific community.
