I Know What I Mean but Only See How You Act
by Darcy Cowan in Skepticon
When I’m writing one of these posts it is difficult to edit them in such a way as to convey my meaning clearly to those without the background I share. I’m not talking about scientific or technical background though, I mean the background that allows me access to my own thoughts. When I re-read my [...]... Read more »

I’m Certain That I Can Certainly be Wrong or Confidence and Memory, Is one a Good Measure of the Other?
by Darcy Cowan in Skepticon
A man is the sum of his memories, you know, a Time Lord even more so.
The Doctor, in “The Five Doctors”
We all know that our memories can’t always be trusted, time and life tends to erode the confidence we have in our memories. At least that is the case for normal memories. We also tend [...]... Read more »

Intelligence, Monogamy and Journalistic Licence
by Darcy Cowan in Skepticon
Last week news came out about a study linking intelligence with liberal attitudes and atheistic beliefs, oh and in men an increased tendency for monogamy. Today I read the NZ Herald’s short take on the study, a semi-chauvinistic piece pointing out how we evolved intelligent men can think our way to monogamy while those sexually [...]... Read more »

Delayed Gratification = Success?
by Darcy Cowan in Skepticon
Today we are going to step into the time machine and go back 21 years to 1989. It was in this year that the study to become known as the “Marshmallow experiment” was published. Performed by Walter Mischel at Stanford University this experiment showed an amazing thing, that testing a child’s self-control at 4yrs could [...]... Read more »

Are Vegans and Vegetarians More Empathic Than Omnivores?
by Darcy Cowan in Skepticon
Humans are naturally omnivorous, our digestive system is adapted to cope with both animal and vegetable matter. Obviously we can’t eat everything, we wouldn’t get as much sustenance out of a mouthful of grass as a cow does. Termites can deal with the high cellulose content of wood and derive energy from that source while [...]... Read more »

Like I Needed Another Reason To Lose Weight
by Darcy Cowan in Skepticon
Now it turns out that in addition to all of the other health risks of being overweight we have to worry about, we are also in greater danger in car crashes. At least for us men.
Men tend to carry a larger proportion of their mass in the upper body than do women. The purpose [...]... Read more »

Can Our Fantasy Life Affect Our Perceptions of Real Life?
by Darcy Cowan in Skepticon
Recently there’s been a television promotional advertisement that really bugs me. It shows a man watching events appearing before his eyes and has a voice-over that says something to the effect of “When you look back on your life are you going to see a life filled with interesting people and excitement?” and when is [...]...

Is there a Biochemical Marker for Suicide?
by Darcy Cowan in Skepticon
Suicide is a sensitive subject, by it’s very nature it seems we are obliged to treat it with kid gloves. In public it is virtually taboo to even mention suicide, in news media euphemisms are employed in order to avoid explicit use of the “S” word. Attitudes are beginning to change, with more vocal discussion [...]... Read more »

Seducing Scientists into Science Communication
by Darcy Cowan in Skepticon
When it comes to science communication I (and I assume many of the bloggers I am aware of though I’d rather not put words in their mouths) do so because of a perceived lack in the mainstream media (MSM). Along with this is a frustration with the amount of unscientific thinking among the general public, [...]... Read more »

Intelligent Design Flaws: The Evidence for Natural Selection in Our DNA
by Darcy Cowan in Skepticon
Here in New Zealand the debate between religion and evolution is a muted affair, while news on the topic regularly makes headlines in the US, here it goes almost beneath notice. That is not to say the clash does not exist here, merely that it tends not to intrude into the public sphere. Over time [...]... Read more »

Does Your Environment Determine Your Behaviour?
by Darcy Cowan in Skepticon
Last week I posted about the effects of alcohol availability on the amount of violence in an area and mentioned that disorder in the area might also contribute to this. I thought this needed expanding upon, are we really so shallow as a species that we allow the environment that we may be in only [...]... Read more »

Is there Something Fishy about Psychosis?
by Darcy Cowan in Skepticon
Psychosis is a scary word, conjuring images of people who have so lost touch with reality that they are unable to integrate with society. As with most everything else this condition exists on a continuum, mild symptoms may pose no problem for the sufferer1 nor be outwardly visible. Previous studies have seen correlations between the [...]... Read more »

Alcohol: Effects on Teenage Brains and Correlations Between Availability and Violence
by Darcy Cowan in Skepticon
I’ve written previously about the effects of alcohol on decision making. Today I’ll be looking at two further aspects of alcohol consumption and how it affects society. First up is a study that examines the cognitive effects of moderate to heavy drinking during adolescence, with different effects on males versus females. Secondly I’d like to [...]... Read more »

A Side Benefit of the ‘Flu Vaccine – Reduction in Heart Attacks
by Darcy Cowan in Skepticon
It’s a bold claim, that being vaccinated for Influenza will protect you against having a heart attack or Myocardial Infarction (MI). Well according to a study published last month in the Canadian Medical Association Journal that could well be the case. The study, “Influenza vaccination, pneumococcal vaccination and risk of acute myocardial infarction: matched case–control [...]... Read more »

Pharmacy Customers Perception of Complementary and Alternative Medicine in Pharmacies
by Darcy Cowan in Skepticon
Going through the papers cluttering my inbox I found this survey of Australian pharmacy customers relating to their use of CAM and their impressions of how pharmacists should approach the subject. Regular readers of Sciblogs may remember a kerfuffle earlier in the year regarding the sale of homeopathic remedies in pharmacies, I and others were [...]... Read more »

The Risky Business of Hunger
by Darcy Cowan in Skepticon
We like to think of ourselves as rational actors when it comes to making decisions, we take in information, process it and choose the path that we think will lead to a desirable outcome (if we aren’t deep-seated masochists I suppose). Regular readers of this blog and others that espouse a sceptical viewpoint will know [...]... Read more »

BioFuel Cell Batteries May Power Future Implanted Devices
by Darcy Cowan in Skepticon
When I think about the future I sometimes indulge in fantasies that include “bionic” type implants. Not so much artificial muscles that will enhance strength (check this out) but devices that will expand our mental capabilities. Implants that give us greater memory, faster thought processes, the ability to download skills and knowledge directly into our [...]... Read more »

Dig-in Or Adapt: The Effect of Political Views on Changing One’s Mind
by Darcy Cowan in Skepticon
Are you the sort of person who will change their position on a subject conditional on further information gained? I personally think this is the behaviour we should all be striving for. If we do not we end up withdrawing further and further from reality, insulating ourselves from rational argument and retreating into our own [...]... Read more »
