\"Craxy“Myth Debunked: Full Moon Does Not Increase Incidence of Psychological Problems,” says the headline on a story on Science Daily<\/a>. I was amused by the notion that, in 2012, anyone would seriously believe that the moon affected human psychology – especially supposed educated people.<\/p>\n

In this case, it was very<\/em> serious and resulted in a paper with the lengthy and ponderous title, “Impact of seasonal and lunar cycles on psychological symptoms in the ED: an empirical investigation of widely spread beliefs.” The abstract<\/a> says:<\/p>\n

This study evaluates the impacts of seasonal and lunar cycles on anxiety and mood disorders, panic and suicidal ideation in patients consulting the emergency department (ED) with a complaint of unexplained chest pain (UCP)… Patients with UCP\u00a0were recruited\u00a0from two EDs. Psychiatric diagnoses were evaluated\u00a0with the Anxiety Disorders Interview Schedule for DSM-IV… Significant seasonal effects were observed\u00a0on panic and anxiety disorders, with panic more frequently encountered during spring [odds ratio (OR)=1.378, 95% confidence interval (CI)=1.002\u20131.896] and anxiety disorders during summer (OR=1.586, 95% CI=1.037\u20132.425). Except for one significant finding, no significant effects of lunar cycles were observed. These findings encourage ED professionals and physicians to abandon their beliefs about the influence of\u00a0lunar cycles on the mental health of their patients. Such unfounded beliefs are likely to be maintained by self-fulfilling prophecies.<\/p><\/blockquote>\n

Whew<\/em>. Although the full text of the report isn’t available to non-subscribers, the article on Science Daily explains:<\/p>\n

…researchers … focused specifically on 771 individuals who showed up at the emergency room with chest pains for which no medical cause could be determined. Psychological evaluations revealed that a sizeable number of these patients suffered from panic attacks, anxiety and mood disorders, or suicidal thoughts.
\nUsing lunar calendars, the researchers determined the moon phase in which each of these visits occurred. The results of their analyses revealed no link between the incidence of psychological problems and the four lunar phases.<\/p><\/blockquote>\n

That struck me as the study’s face-palm moment, the time when the Simpsons’ “Doh!” should have been shouted by the researchers as they smashed their palm into their heads.<\/p>\n

“Geez,” one of them must have said as the data came in, “I’ll bet if we explore this further, we’ll also find out Friday the 13th is no more unluckier\u00a0than any other day. What next? Black cats aren’t bad luck? We can safely walk under ladders? We don’t need to toss salt over our left shoulder when we spill it? Saying “gesundheit” when you sneeze doesn’t keep demons away? When will it end?”<\/p>\n

That so-called “link” between behaviour and lunar cycles\u00a0is merely a hangover from the discredited pseudoscience of astrology; it oozes from our ancient past when superstitious cave people believed the planets and stars were gods and demons and could affect our lives. Believing lunar phases can affect psychology today is akin to believing magnets or crystals can make you healthier. Pure and simple balderdash. It’s not a great leap from believing astrology to believing in creationism and Scientology, or that vaccines are a government conspiracy to enslave you.<\/p>\n

The researchers also found that “anxiety disorders were 32% less frequent during the last lunar quarter.” Their analysis of this statistical oddity?<\/p>\n

“This may be\u00a0coincidental or due to factors we did not take into account,” suggested Genevi\u00e8ve Belleville. “But one thing is certain: we observed no full-moon or new-moon effect on psychological problems.”<\/p><\/blockquote>\n

Coincidental? You think<\/em>? What’s the other choice? That the moon made people less anxious one week every month? Come on… what next? Lycanthropy?<\/p>\n

But what’s scary is that, according to the study, the majority of\u00a0medical professionals BELIEVE that the moon affects personality and mental health. These are the people into whose hands we entrust our well-being! We expect them to be scientific, observant, and logical – even skeptical and suspicious (skepticism is what\u00a0drives intelligent inquiry). Not medieval, not superstitious, not silly. If I want that, I can find it in copious amounts on the Net. When doctors start believing in astrology, I expect them to trot out the “healing crystals” for my bad humors, or kill a chicken to cure my possession.<\/p>\n

This study’s conclusions run contrary to what many believe, including 80% of nurses and 64% of doctors who are convinced that the lunar cycle affects patients’ mental health. “We hope our results will encourage health professionals to put that idea to rest,” said Dr. Belleville. “Otherwise, this misperception could, on the one hand, color their judgment during the full moon phase; or, on the other hand, make them less attentive to psychological problems that surface during the remainder of the month.”<\/p><\/blockquote>\n

“Color their judgment”? Break out the ouija board then next time you go to your doctor, because if he or she believes the moon is influencing your state of mind, you better contact the spirits for answers. Or better yet, run for the exit.<\/p>\n

Oh wait. There are no<\/em> spirits. No<\/em> ghosts, no<\/em> goblins, no<\/em> orcs, no<\/em> Easter Bunnies, no<\/em> demonic possession, no<\/em> vampires, no<\/em> werewolves, no<\/em> angels, no<\/em> psychics, magic crystals don’t cure disease and magnets don’t make you healthier. Astrology is bunk. Palmistry is bunk. Phrenology is bunk. Sorry to have to break the news.<\/p>\n

Wait a second. This isn’t the first study to debunk this particular silliness. It’s the umpteenth. According to the Skeptics’ Dictionary<\/a>:<\/p>\n

Ivan Kelly, James Rotton and Roger Culver (1996) examined over 100 studies on lunar effects and concluded that the studies have failed to show a reliable and significant correlation (i.e., one not likely due to chance) between the full moon, or any other phase of the moon, and each of the following:
\n-the homicide rate
\n-traffic accidents
\n-crisis calls to police or fire stations
\n-domestic violence
\n-births of babies
\n-suicide
\n-major disasters
\n-casino payout rates
\n-assassinations
\n-kidnappings
\n-aggression by professional hockey players
\n-violence in prisons
\n-psychiatric admissions [one study found admissions were lowest during a full moon]
\n-agitated behavior by nursing home residents
\n-assaults
\n-gunshot wounds
\n-stabbings
\n-emergency room admissions [but see]
\n-behavioral outbursts of psychologically challenged rural adults
\n-lycanthropy
\n-vampirism
\n-alcoholism
\n-sleep walking
\n-epilepsy<\/p><\/blockquote>\n

Gosh. the moon doesn’t affect ANYTHING*<\/span>. Must be bad research. Let’s try again… maybe justify our research grants… when do we stop repeating this stuff?<\/p>\n

Okay, folks, let’s agree that this issue is finally settled with this, the umpteenth-and-one study. Don’t waste any more time chasing shadows, not on my tax dollars. It’s been debunked many, many times. Let it rest and focus your attention on real science. Please don’t follow this up with a study on black cats or Friday thew 13th.<\/p>\n

~~~~~<\/p>\n

*<\/span> Also\u00a0from the Skeptics’ Dictionary:<\/p>\n

Many believe in lunar myths because they have heard them repeated many times by members of the mass media, by police officers, nurses, doctors, social workers, and other people with influence.\u00a0Once many people believe something and enjoy a significant amount of\u00a0communal reinforcement<\/a>, they get veryselective<\/a>\u00a0about the type of data they pay attention to in the future. If one believes that during a full moon there is an increase in accidents, one will notice when accidents occur during a full moon, but be inattentive to the moon when accidents occur at other times. If something strange happens and there is a full moon at the time, a causal connection will be assumed. If something strange happens and there is no full moon, no connection is made, but the event is not seen as counter evidence to the belief in full moon causality. Memories get selective, and perhaps even distorted, to favor a full moon hypothesis. A tendency to do this over time strengthens one’s belief in the relationship between the full moon and a host of unrelated effects.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"
