Hello Grimericans! I have a confession to make. And while it doesn’t really pain me to admit it, this truth about me and my way of thinking has the power to cast doubt on my person; as a person. A logical thinking one, anyway. It is the way I approach anecdotal stories in relation to “paranormal” events. I love them. I thrive off of them if I’m being honest. Nothing keeps me more interested in the strange, weird and otherworldly than the stories of the people who have claimed to have witnessed them. Now the skeptic in me, and in many of you, obviously find this way of thinking as a conflict of interest when one is trying to put their logical, “good” skeptic foot forward. But how harmful is it to indulge in the anecdotes of the supernatural and the like? If one keeps their little ‘s’ skeptic cap on whilst remaining open-minded when this data is learned, then isn’t that how the scientific method is supposed to be approached? With one foot in skepticism and one in the unknown? Moreover, is anecdotal data really worthless? By the way, for the sake of brevity, I will refer to it as anecdotal data as opposed to the more commonly used anecdotal evidence. Because that is really what it is: data, after all. As I’ve pointed out before, the word evidence denotes that the burden of proof is lifted. If that was the case, then it wouldn’t be anecdotal. Not to get too tied up in semantics, but like I said, for the sake of brevity. So let’s strap in and examine some anecdotal data at its best.
Whoa, whoa… Hold on a second…
Now I know most of you are probably critically thinking, skeptically minded individuals who won’t just accept any story without solid proof, or at least strong data, to at least cast a shadow of possibility on someone’s claims. And given the nature of anecdotes and what some “big S Skeptics” might rightfully point out that most anecdotal evidence is cherry-picked, you might not want to read what this article is about. I mean, the title of this post is “Anecdotal Evidence at [it’s] Best”. But before you hand in that skeptic card, please remember the importance of anecdotal data in regards to science. Hell, the importance of it in everyday life. Humans have ALWAYS used anecdotal data as a starting point to a clear answer. Sometimes it takes longer than other times and more than likely, not everyone will agree with the result. I’m not saying that EVERY important discovery was the result of some chestnut of personal experience or observation, but a lot have. Things like…
Bioelectricity and the Battery
Eighteenth century biologist, physicist and physician Luigi Galvani was dissecting a frog on a table that was previously used for experiments with static electricity. To his surprise, he noticed that when he touched a brass hook that held the frog’s leg with his metal scalpel that had acquired a charge, the muscle contracted and probably made him jump (Galvani, not the frog). This made him raise an eyebrow (and probably change his pants) and he investigated further. He then reported that he believed he had discovered what he called animal electricity. He thought it was a life force within the muscles of the animal. A contemporary of his, Allesandro Volta, was able to reproduce Galvani’s results but remained skeptical of his explanation. He proposed the resulting contraction what due to the contact of the two metals and external electricity and the frog’s muscle was only a detector or the small differences of the external source. To try to prove this, he invented the first true battery, known as the Voltaic Pile, to aide in the experimentation to disprove Galvani’s claims. So, if you’re reading this on a mobile device, that battery that powers it is one of the side results of what started out as anecdotal evidence… just saying. While Galvani was eventually proven wrong, it was his raised eyebrow that started humans down the path of what is now known as electrochemistry. The Voltaic Pile also led to accelerated discoveries such as the electrical decomposition of h2o into hydrogen and oxygen, as well as the isolation of the seven chemical elements including calcium, potassium and magnesium by Humphry Davy. Volta was such a nice guy, he still named that process of electricity produced by a chemical reaction after Galvini, galvanism.
The Microwave Oven
One day in 1945, American born engineer Percy Spencer was building magnetrons for Raytheon and was standing in front of a live radar set when he noticed that a candy bar in his pocket had melted. After getting over the loss of his mid-day snack, he began a mission to figure out was caused the premature end of his favorite munchies and vowed revenge. Okay, the revenge might be a little exaggerated. Just making sure you’re still paying attention. And while he wasn’t the first to notice the effects of microwaves on food, he was the first to investigate further. The result of that investigation being the microwave oven and all of your favorite, “no time to cook a real meal’ meals that you’ve come to love. Percy Spencer, you’re my hero..
Yep. Evolution. It was the anecdotal observations of Charles Darwin that led him down the path of discovery of one of the greatest revelations in history. I think everyone is well versed on this topic that I don’t have to cover it in detail. But I would be remise if I didn’t mention that when Darwin first published his theory in his book “On the Origin of Species” he was met with overwhelming rejection from the scientific community. Evolution not good enough for ya’? How about…
Okay, this is an anecdotal story of an anecdotal story. A young Sir Issac Newton was resting under an apple tree when the winds of fate blew an apple down and struck the young genius on his crown. It was this event that made Newton ponder and conceive the idea of gravity. Or some variation of that story. The tale has long been called apocryphal. Fortunately, a manuscript by William Stukeley that would later go on to become a biography on the apple catching scientist, was found hidden away in the archives of the London’s Royal Society. The story about the apple was relayed to Stukeley by Newton himself and it follows as such:
“After dinner, the weather being warm, we went into the garden and drank thea, under the shade of some apple trees…he told me, he was just in the same situation, as when formerly, the notion of gravitation came into his mind. It was occasion’d by the fall of an apple, as he sat in contemplative mood. Why should that apple always descend perpendicularly to the ground, thought he to himself…”
So the apple story was true. Well, mostly. The point is, anecdotal data sparks the imagination and can start the process of inquiry. Imagine where we’d be as a culture if we never acted on those inspirations. And while I do think it’s important to remain skeptical, I also believe it’s just as important to imagine. I think some forget that latter part. Here is a link to an article that I found very useful and insightful about the importance of anecdotal data. They provide a huge selection of links from Wikipedia that shows historical examples of serendipity that show the importance of anecdotal data. In case you don’t want to click the linky-link, I took the time to copy and paste them below. I will provide a quote from the article for those who feel like this post was long enough and don’t feel like reading any more:
“The most important statement a scientist can make is, ‘Huh, that doesn’t make sense. That shouldn’t have happened.'”
Well that’s it for me Grimericans. Stay classy.

- The dye monastral blue was discovered in 1928 in Scotland, when chemist A. G. Dandridgeheated a mixture of chemicals at high temperature in a sealed iron container. The iron of the container reacted with the mixture, producing some pigments called phthalocyanines. By substituting copper for iron he produced an even better pigment called ‘monastral blue’, which became the basis for many new coloring materials for paints, lacquers and printing inks.

- Mustine – a derivative of mustard gas (a chemical weapon), used for the treatment of some forms of cancer. In 1943, physicians noted that the white cell counts of US soldiers, accidentally exposed when a cache of mustard gas shells were bombed in Bari, Italy, decreased, and mustard gas was investigated as a therapy for Hodgkin’s lymphoma.
- Prontosil, an antibiotic of the sulfa group was an azo dye. German chemists at Bayer had the wrong idea that selective chemical stains of bacteria would show specific antibacterial activity. Prontosil had it, but in fact it was due to another substance metabolised from it in the body, sulfanilimide.

Physics and astronomy
- The quite possibly apocryphal story of Archimedes‘ prototypical cry of Eureka when he realised in the bathtub that a body’s displacement water allowed him to measure the weight-to-volume ratio of any irregularly shaped body, such as a gold crown.
- Isaac Newton‘s famed apple falling from a tree, supposedly leading to his musings about the nature of gravitation.
- Discovery of the planet Uranus by William Herschel. Herschel was looking for comets, and initially identified Uranus as a comet until he noticed the circularity of its orbit and its distance and suggested that it was a planet, the first one discovered since antiquity.
- Infrared radiation, again by William Herschel, while investigating the temperature differences between different colors of visible light by dispersing sunlight into a spectrumusing a glass prism. He put thermometers into the different visible colors where he expected a temperature increase, and one as a control to measure the ambient temperature in the dark region beyond the red end of the spectrum. The thermometer beyond the red unexpectedly showed a higher temperature than the others, showing that there was non-visible radiation beyond the red end of the visible spectrum.
- The thermoelectric effect was discovered accidentally by Estonian physicist Thomas Seebeck in 1821, who found that a voltage developed between the two ends of a metal bar when it was submitted to a difference of temperature.

They planned to use the occultation of the star SAO 158687 by Uranus to study the planet’s atmosphere, but found that the star disappeared briefly from view five times both before and after it was eclipsed by the planet. They deduced that a system of narrow rings was present.
- Pluto‘s moon Charon was discovered by US astronomer James Christy in 1978. He was going to discard what he thought was a defective photographic plate of Pluto, when his Star Scanmachine broke down. While it was being repaired he had time to study the plate again and discovered others in the archives with the same “defect” (a bulge in the planet’s image which was actually a large moon).
- High-temperature superconductivity was discovered serendipitously by physicists Johannes Georg Bednorz and Karl Alexander Müller, ironically when they were searching for a material that would be a perfect electrical insulator (nonconducting). They won the 1987 Nobel Prize in Physics.
