Homeopathy, a belief from 200 years ago that if you took something that mimicked the symptoms of a disease you could prevent a disease, or that extremely diluted water with a molecule of something will be curative, has never been shown to work in any clinical trial.

Nonetheless, some people swear by it, much as people believe other placebos. What to do if your doctor recommends it? In the United States, a doctor is ethically forbidden from prescribing a placebo outside a clinical trial, but it is known some do. And lots of folk medicine/alternative medicine/integrative medicine people will claim it works if you believe it works. 

In 1907,Francis Galton recorded the entries from a competition where people guessed the weight of an ox. After analyzing hundreds of estimates the statistician found that while individual guesses varied wildly, the median of the entries was surprisingly accurate, within one percent of the ox's real weight.

Galton published the results and his theory of collective intelligence, the "wisdom of crowds," became part of the lexicon.

Advocates are claiming medical marijuana can help to fight the opioid epidemic but data show the opposite. Rather than being at lower risk, people who use medical marijuana may be at higher risk for non-medical prescription drug use.
Much of medical marijuana usage was always recreational and a new study in the Journal of Addiction Medicine finds that people who use medical marijuana have higher rates of prescription drug use - including pain relievers.

Does Use of Medical Marijuana Increase or Decrease Prescription Drug Use?

This is another of my posts to help victims of fake doomsdays. For the last three weeks we've had constant PM's and comments on Doomsday Debunked as a result of a viral hoax that pranked probably hundreds of thousands of people worldwide. Many of them are young children still at school who came across it on social media, on twitter, Facebook, reddit or YouTube, or as a result of the sensationalist press.

Though we read a lot of claims about impending extinction, the biological reality is that we don't know anything about 99.9999999 percent of species that have ever lived. And then there are species only newly discovered that are immediately declared endangered because an academic only recently named them in a print journal.
The mix of bacteria (microbiome) of bee bread, the long-term food supply stored within a hive for young bees, is now at risk, according to a new estimate.

The scholars are blaming modern monoculture farming, commercial forestry and gardeners could be making it harder for honeybees to store food and fight off diseases, a new study suggests. Human changes to the landscape, such as large areas of monoculture grassland for livestock grazing, and coniferous forests for timber production, is affecting the diversity of the ‘microbiome’ associated with honeybees’ long-term food supply, the authors claim. 
One of the most fundamental predictions of Einstein's theory of relativity is the existence of black holes.

Although gravitational waves from binary black holes have been detected, direct evidence using electromagnetic waves hasn't happened and astronomers are searching for it with radio telescopes.  But then how can you tell them apart? Radio images have a limited resolution and image fidelity and at realistic image resolutions, even highly non-Einsteinian black holes seem like normal black holes.

This is going viral on Facebook and scaring thousands of people, many panic attacks, some suicidal. This is another of my Doomsday Debunked posts to help these vulnerable people, many of them young children, still at school, who read about this on their mobile devices. Ever since March 14th I've spent hours every day reassuring very scared and panicking people that the MH 370 flight recorder did not send a voice mail message to a random twitter user warning us of an alien invasion on 18th April. Honestly‽

This is a piling heap of stinking horse dung that attracts trolls like flies and beetles from thousands of kilometers away. Like the Titan Arum or Corpse Flower.

More competitive animal species, with males that compete intensively for mates, might be more resilient to the effects of climate change, according to a paper in Proceedings of the Royal Society B. Sexual selection can provide a buffer against climate change and increase adaptation rates within a changing environment, the authors believe.

Moths exposed to increasing temperatures were produced more eggs and had better offspring survival when the population had more males competing for mating opportunities, three males for every female. 
Any justification is fundamentally deception because there is no link from fundamental meaninglessness to why I should go on living. My a priori finding myself embodied in a world and the necessary physical causal creation myth involving emergence by algorithmic evolution necessitates my finding myself evolved to keep on living as one main irrational basis underlying all my rationalizations (for any evolved observer in any possible world).
