There aren’t any absolute claims in science (maybe). Science can provide a body of useful information and try to show us nature’s patterns.
Yet the universe is too enigmatic to be reduced to a list of things to do and things not to do. A fundamental principle of toxicology puts it well:
The dose makes the poison.
If you’re reading something that you have reason to disagree with, by all means share it! Write a post, list your sources, and tell the other side of the story.
The greater the number of different points of view included in a community, the more likely its scientific practices will be objective.
~Dr. Helen E. Longino, philosopher of science
