It’s the end of another year; time to consider a few
resolutions. The trouble with
resolutions is they take will power. The
dimension of discipline comes into play.
Why can’t there be some easy resolutions that are more about not doing something
than about working hard. That should
make things considerably easier, and more rewarding in terms of that feeling of
success.
A Christmas visitor directed me to this website. The title of the article is “7 bad science
and health ideas that should die with 2016.”
The authors write about how some wrong ideas just seem to stick
around. Friends tell friends. Ideas become ingrained, and despite all the
good science to the contrary, they just won’t go away. According to the article, this particularly
applies to seven myths “that were decisively debunked this year” or possibly
debunked again in one more attempt to make them go away.
This is one of my personal favorite subjects; the things
people continue to believe and refuse to change their opinion despite
overwhelming contrary evidence. Instead they
look to social media friends or their favorite echo-chamber news source for
reassurance. Throughout the last five
and a half years I have brought up many of these subjects. (For a few of my examples, just look to the
history over the last six months where the title begins, “One More Time.”)
In this case though, since these are bad ideas, shown to be
decisively incorrect, a good and easy New Year’s resolution would be simply to
stop believing them.
The first myth – Exercise will help you lose weight. Many studies show that “the extra calories
you burn only account for a small part of your total energy expenditure, and
that cutting your food intake is a much more efficient way to lose weight.”
The actual myth should read "increasing exercise alone would lead to significant and lasting weight loss." Exercise is really good. It gets the blood pumping, which is good for the heart, and good for the bones and good for the brain. It even helps reduce the chance of getting certain diseases. But no one can increase exercise while maintaining the same diet and lose much weight. Unfortunately, it doesn’t work that way. Programs led by the NFL and the First Lady are not going to impact the childhood obesity epidemic unless diets change also. We could all start running marathons and it wouldn’t help.

The second myth – There’s been no global warming since 1998. They present several charts and graphs to
point out that the temperature has increased over that period. There have been ups and downs – not unusual
for a small data set, in this case less than 20 annual observations. These ups and downs have
led some to doubt whether the warming has persisted. But the temperature has been increasing for
the last 400 years, so the fact that we have not had a dramatic flattening or change
of direction should surprise no one.
This myth misses the key questions about climate change. Warming is not the issue. The major questions are: first, whether actions prescribed will have any measurable effect on the warming, and second,
whether the change in climate will be catastrophic. The assumed answer to both these questions is
yes. But the large consensus about
warming does not extend to these assumptions. The danger is that if the answer to either is
no, we have wasted a lot of resources, resources that will be needed to adapt
to a catastrophic change if it comes or resources that will be completely
wasted. In the latter case we will have
sacrificed some our standard of living and deprived third-world countries of
the ability to improve theirs significantly for nothing. Of course none of that matters because debate
is closed.
The third myth - Antibiotics cure colds. This is simple. Antibiotics kill bacteria. Viruses cause colds. Bacteria and viruses are not the same. But people take antibiotics and the cold goes
away. People also take vitamin C,
Echinacea, zinc and other products and the cold goes away. Then they all swear by the effectiveness of
whatever they tried. Of course, some
people take nothing and the cold goes away.
The particular danger with antibiotics is that “the more we
take antibiotics – particularly when they're not necessary – the more we
increase the chances of helping develop antibiotic-resistant bacteria.” A second concern is that they can wipe out
good bacteria in our guts. A third
problem is that it’s a waste of money.
Some good, easy resolutions would be to drop the idea that
exercise alone will be an effective weight loss program, to admit the earth is
warming but not to panic over every dismal prediction, knowing that dismal
predictions drive so much funding, and to lay off the antibiotics unless
prescribed for a bacterial infection.
Come back Monday for a few more easy resolutions.
