As a physicist, I understand what science is about. I have a good understanding of the scientific method and what science has achieved. But, unlike many other physicists it seems, I also know about the limits of science.
So, recently, I saw this “pledge for science” where people are asked to add their support to say that they put their trust in science. Unfortunately, I could not find a fully worded statement of this pledge to understand exactly what is meant by it. What does it mean to put your trust in science?
To be honest, I think I know where this is coming from. With all the anti-vaxxers, followings on the heals of global warming denial, and all those kinds of trends and misinformation that is being spread via social media, it is not surprising that some reaction would follow from the scientific community. However, one needs to guard against an over-reaction.
Science does not have a clean track record. It is unfortunately responsible for several serious problems in our world today. Take for instance global warming. It does not take much to realize that in as far as it is caused by human activity, it is with the aid of scientific development that this human activity is able to cause global warming.
Another example is weapons of mass destruction. Through scientific investigation humanity achieved the point where it can cause unprecedented death and destruction. Not exactly a highpoint in human cultural achievement. Once this door was opened, nothing could close it again. Forever, humanity will have this sword having over its head.
One can proceed to list other negative effects of scientific development such as pollution and the hole in the ozone layer, but I think the message is clear by now. An unconditional trust in science is a very dangerous thing. Instead, one should rather support an effort to get people educated and informed, not only about science and the scientific method, but also about other aspects of culture. For instance, if people have better knowledge of history, they would have a better understanding of how ignorance can lead to terrible things.
Let me emphasize then, I do not support an unconditional pledge to put my trust in science. In fact, it is a dangerous thing to put one’s unconditional trust in any specific thing on this earth.
