The method is sound. The application of it usually is. Yet sometimes other very human forces take over. Hopefully over time truth gets sifted out through it but it’s always good to keep both eyes open.
Look at religions. Many of them, at their core, are very good and useful systems, when they stick to their ideals. Being a Christian at its core is being a good person in theory.
But then there’s the application.
The practice of science, also made up of humans, suffers from the same issues.
Global warming is a strange case; it was a purely scientific issue until 1988, with the formation of the IPCC. Then everything past that point had a different character, a different push. Pure science on the issue was no longer really possible, as there was a carrot on a stick now.
This doesn’t mean there wasn’t and isn’t good science being done within. I believe there is. Yet, still, when they get mixed together, it always leaves me with an awkward feeling.
