Lunar Cycle Effects Busted

steven_novellaBy via NeuroLogica Blog

When I was an intern doing a rotation in the emergency department, on one particularly busy shift a nurse commented (to no one in particular) that it must be a full moon. I habitually look at the moon and generally know what phase it is in (right now it is a waxing gibbous, almost full), and so I knew at the time that in fact there was a crescent moon in the sky. I informed her of this. She gave a disappointed look and then went on with her work without any apparent further thought on the matter.

The episode struck me at the time. It seemed to me that I just witnessed a clear example of confirmation bias – what if it had been near a full moon?Moon_Animated_250px That would have confirmed her prior belief in a lunar effect, while this negative correlation was brushed aside and likely did not have any negative effect on her belief. (Although, my interpretation and memory of this event can itself be an example of confirmation bias regarding confirmation bias.)

Belief in the so-called lunar effect, that the phases of the moon exert an influence on human behavior with the most common element being a full-moon inducing extreme behavior, is very common. In my experience it is one of the most common pseudoscientific beliefs I encounter in the general public. One survey indicates that 43% of adults believe in the lunar effect, especially mental health professionals, including nurses.

When someone expresses such a belief to me I often use it as an opening to discuss skeptical principles. While belief in the lunar effect is widespread, it is usually not part of any emotionally held religious or ideological belief. It is therefore an excellent teaching opportunity. One question I like to ask is, “how do you think that works?” The most common answer I receive is probably the least plausible – that the tidal effects of the moon influence the brain because the brain is sitting in water (spinal fluid).

The tidal effect answer is incredibly implausible for a number of reasons.

Investigating the Rhode Island UFO

By Chip Taylor via The Committee for Skeptical Inquiry – CSI

With a half a century plus of interest in UFOs, astronomy, and science, I’ve despaired that in all that time I’ve never seen a real UFO. (With emphasis on what the “U” stands for of course.) I’ve seen bolides (really bright meteors), nighttime aerial refueling operations by USAF jets, odd contrails, space satellites, balloons, kites, birds, and insects. Some of these were initially unidentified, but only for a brief moment. Thus it was fascinating, weird, puzzling, and astonishing that in September of 2012 I actually got to see a real UFO that didn’t seem to fit any sort of known aerial object.

The mysterious Rhode Island “UFO.”

The mysterious Rhode Island “UFO.”

On a pleasant Sunday afternoon I was participating in a ham radio contest on Block Island, which is about a dozen miles off the Rhode Island mainland. It was one of those casual contests where there is plenty of free time to enjoy the day and watch the views. And there were a lot of things to watch. My friend and I were on an open roof deck of a house on the highest point of the Island on a crystal clear day with visibility to the horizon. ufo rhode-island_250pxBinoculars at hand, I was watching planes come and go at the nearby airport, sailboats off shore, an advertising blimp hovering between Narragansett and Newport, and birds flying about. Not a thing out of the ordinary.

And then, through the binoculars, I suddenly saw it: some kind of craft or “thing“ flying parallel to the distant shore at an estimated speed of perhaps thirty miles per hour. Too far away to see without binoculars, and even with them all I could make out was a parallelogram-shaped craft moving very slowly and into the wind. There was no sign of anything towing it and no sign of wings or motors. That was strange enough, but as it moved along it seemed to change shape: sometimes it was almost square, sometimes almost cigar shaped, but often getting shorter or longer as I watched. camera_225pxThe shoreline was about eight or nine miles away I guessed, and if this object was directly above the beach then it would have to be quite large—dozens of feet long and high.

I watched for several minutes and finally thought to take a photo or two. About a minute afterward it dove steeply down and disappeared behind some low hills that were a short distance behind the beach. That steep dive seemed unusual. What was back there? Where did it go? What was it? Well, I was in the middle of a radio contest (My partner was so engrossed with the radio he didn’t even bother to check out this weird craft), I was quite comfortable that I wasn’t seeing alien visitation or biblical angels, so an investigation would have to wait.

Once back home it was time to see if I could determine just what it was that I saw.
