It looks like Tennessee can add another dumb law to join the ranks of other special ones such as being able to shoot whales out of a car, marrying your cousin, and not being allowed to carry skunks into the state or electrifying your trash. It now joins Louisiana in being one of the only two states to have anti-evolution and anti-climate laws in effect.
The National Center for Science Education (NCSE) recently posted their yearly anti-science legislation scorecard. It tallies up all the bills that states tried to pass over the past year attempting to interpose more “objectivity” into science curriculum.
Normally objectivity in science isn't a bad thing, in fact it's quite necessary and essential. However, these state legislatures' brand of objectivity means questioning well-proven theories like evolution and climate change, which are supported by mounds of evidence and have earned consensus among (legitimate) scientists.
Recall that a “theory” in science has a different connotation than when everyday people use it. A scientific theory has been rigorously tested and reviewed by multiple experts by the time it's assigned that label.
