A must read as a main tenet of practical skepticism.
The next time you hear about interesting findings from the latest scientific study on health, be sure to pay attention to the subject of the study. Was it done on mice? Then don’t get too excited and don’t immediately change your lifestyle because of it.
Mice (and rats, fruit flies, zebrafish, roundworms – all common experimental subjects) are not people. Sorry to be so obvious but it’s easy to miss this when the news anchor on Good Morning America is just so enthusiastic. Results from experiments on them do not necessarily translate to results in humans. Human trials are an additional step – one that is difficult and expensive – so experiments on animals will occur first to provide data and decide whether to move ahead to human trials.
Here are some examples of studies that got widespread press coverage with headlines the sounding promising. But, the fact that they were done on mice might have been missed. Continue reading
Information is not the same as KNOWLEDGE. We are barraged with information. Constantly. And I’d guess more than half of it is unsubstantiated, not quite right, or downright untrue. Knowledge takes more effort. It’s a consideration of the information and placing it into a framework of how the world is or a model of the way things work. Information can mislead as often as lead. Knowledge can be enlightening and is part of who you are.
We can always use more knowledge. We can probably do with less information. Quality information is only what’s good for most of us (unless you are in a profession that can capitalize on bad information).
Here’s where the skepticism comes in. Continue reading
Practical skepticism means using critical thinking everyday. Sometimes the news sounds TOO RIDICULOUS to be true. That should be a flag to question it or at least read VERY carefully before passing it on. A recent story about a North Carolina town who rejected solar panels was not quite what the headlines said it was. I wrote about it over at Doubtful News.
Sure, two commentators (who may be related) said at a public council meeting they had some concerns about the proposed solar farm — that it would mess with photosynthesis of plants and suck up all the energy from the sun. But those weren’t direct quotes and we aren’t clear exactly what was meant or the context. Perhaps they misspoke or meant something a bit different than how it was reported.
This is not a fairy tale.
Once upon time, top scientists of the day expected to discover a genuine monstrous sea serpent that sailors said they saw with their own eyes. The ocean was and still is a source of rich stories of strange encounters with mysterious beasties.
There are hundreds and hundreds of “sea serpent” reports from around the world. (And, mind you, that’s just from the sea, not from lakes or rivers!) They originated with ancient sea-going cultures – Scandinavia, in particular – and the tales travelled around the world just as fast as people could travel.
One of the most famous sea serpent sightings given serious scientific inquiry has been that of the creature seen by the crew of HMS Daedalus in 1848 after they had rounded the southern end of Africa ( on the west side) in the South Atlantic. The Captain himself reported on the sighting to naturalists and the newspapers of the time: Continue reading
About 20% of Americans do not “believe” in evolution. This piece from BBC News explains evolution in a way you should consider: How Do We Know Evolution is Real
The nifty but harsh thing about scientific knowledge as time-tested and confirmed as evolution is that it doesn’t care if you believe it or not, it still just is.
Evolution just is.
One vulnerable population to scammers is the elderly. They are less likely to be up on the latest scam warnings on social media and they may assume that people are being truthful and not out to deliberately rob them. But they ARE. Our grandmas and grandpas need to keep practicing practical skepticism.
The US Federal Trade Commission is warning people about a trick to get grandparents to fork over money they will never see again. Continue reading
