You Believe What You Want To Believe (Tom Petty)

Scientific research relies on rigorous systematic testing that involves treatment and control groups and extensive peer review to prove or disprove hypotheses. That way we can be confident in the result, regardless of what the findings may be. In reality this is not always the case, people believing what they want to believe regardless of the evidence. Look at the trouble Copernicus and Galileo had trying to convince people that the Earth revolved around the Sun. Sadly, despite being scientifically trained, I am not really any different.

As an example, coffee is a marvellous drink proven, through scientific research, to increase energy levels, improve physical performance, and lower the risk of developing type II diabetes, Alzheimer’s, Parkinson’s, liver cancer and colorectal cancer. Much more spurious research that obviously needs to be repeated with a larger data set seems to link coffee to sleep disturbance, increased blood pressure and raised levels of cholesterol.

The research is similarly biased when it comes to alcohol consumption. I like nothing more than to sit back with my very full glass of red and read how the resveratrol in my Shiraz keeps my heart healthy and further protects me against diabetes and Alzheimer’s. All that nonsense about depression, cancer, cirrhosis and memory loss is surely just that?

The list goes on. Any research that supports an activity I engage in and enjoy is sound while anything that contradicts it is suspect. Science even has a name for this, confirmation bias. I suppose religions would call it faith.
