Science

Knowledge Base: Science

Science is one of the most effective methods for gaining reliable knowledge about the empirical world, from spacecrafts to cures for human diseases and thousands of other profound discoveries. Anti-science activists threaten to undermine the knowledge that science has brought us and want to replace it with misinformation and ignorance.


Fact: Science updates and improves based on evidence

Basic:

Science advances by improving and updating their models based on new empirical evidence. http://wp.me/P18AZ8-o2J

Intermediate:

Scientific research results in hundreds of thousands of publications every year. This is part of a constant process of improving and updating the scientific understanding of the world. New models make the same predictions as older models in areas where they both apply.

Scientific research advances our understanding of the world, from finding new exoplanets to creating new effective treatments for human diseases. New evidence is incorporated into current models by updating and improving these models to fit the evidence. A new and improved model must also make the same predictions as an older one in areas where they both apply (correspondence principle). Humans landed on the Moon using nothing but Newtonian mechanics and did not need general relativity even though the latter is a more accurate model overall. It is because Newtonian mechanics still make highly accurate predictions when velocities and masses are not extremely high.

Some anti-science activists falsely claim that science is always changing its mind based on arbitrary considerations. This is wrong because the models improve, the improvements are based on scientific evidence and new models must make the same predictions as older models in areas where they both apply. Updating and improving models based on evidence is something good, not bad. Refusing to take into account new evidence is ideology, not science.
