Answer the question you selected for profile question 3 here (300 words):
Thinking like a scientist is hard, even for scientists.
It requires putting aside your own prior beliefs, evaluating the quality and meaning of the evidence before you, and weighing it in the context of earlier findings. But parking your own agenda and staying objective is not the human way. Consider that even though scientific evidence overwhelming supports the theory of evolution, a third of people think the theory is “absolutely false”. Similarly, the overwhelming scientific consensus is that human activity has contributed to climate change, yet around a third of people doubt it.
• Five reason it’s so hard to think like scientists
1. We’re swayed by anecdotes: When making everyday decisions, such as whether to begin a new treatment or sign up to a class at university, most of us are influenced more powerfully by personal testimony from a single person than by impersonal ratings or outcomes averaged across many people. This is the power of anecdote to dull our critical faculties.
2. We’re overconfident
Confronted with a scientific claim, another reason many of us find it hard to reflect on it scientifically is that we overestimate our comprehension of the science
3. We’re biased by our prior beliefs
This obstacle to scientific objectivity was demonstrated by a now-classic study from the 1970s in which participants were asked to evaluate scientific research that either supported or conflicted with their prior beliefs.
4. We’re seduced by graphs, formulas and meaningless neuroscience
It doesn’t take a lot to dazzle the average newspaper or magazine reader using the superficial props of science, be that formulas, graphics or jargon.
5. Being smart isn’t enough
Even expert researchers suffer from the human foibles that undermine scientific thinking. Their critical faculties are contaminated by their agenda, by their ultimate motives for doing their experiments.
