If your experience is at all like mine, you might have noticed a recent uptick in conspiracy theories, pseudoscience, and all-around woo. Without speculating about the causes (which might just be confirmation bias on my part), I think it’s desirable to assemble a sort of ‘toolkit’ to react against the most egregious examples.
By that, I mostly mean a collection of what I call ‘fact bombs’: a small collection of well-supported assertions that, together, serves to debunk some common form of woo. So, you might have a ‘why homeopathy is bunk’-fact bomb, a ‘why the Earth isn’t flat’-fact bomb, a ‘no, we really went to the moon’-fact bomb, and so on.
This has two purposes: one, for all of those who are ‘on the fence’ (if there actually are any), you supply a short, self-contained argument warding off the woo; two, ideally, they help averting those long, pointless discussions with the latest tinfoil hat bearer where you keep kidding yourself that maybe the next attempt to explain things might make a difference.
To do so, fact bombs should ideally be easily comprehensible, sufficient to demonstrate the claim being made, and convincing to everyone adopting a rational stance. This is, in all probability, impossible to achieve in practice; but we can try and get as close as is feasible. To this end, I’d like to invite discussion, while discouraging quibbling, if at all possible.
So, I’m gonna start things off with my evolution fact bomb:

[li]Microbial adaptation: it is readily observable in the lab that, e.g., bacteria adapt to adverse stimuli, like antibiotics, by mutation and reproduction.[/li][li]Ring species: along, for instance, coast lines, there exist populations such that each population can interbreed with its neighbors, yet the beginning and end of this chain cannot, and thus, have to be considered separate species.[/li][li]Endogenous retroviruses: the genome contains traces of DNA from viruses that have infected the germ line, which is thus inherited from parent to child. There are numerous identical such loci between different species, such as humans and chimpanzees—the likelihood of this being an accident is astronomically low. Hence, there must be a common origin.[/li][/ol]
What are your fact bombs? Do you have one for 9/11, the moon landings, chemtrails?
