It is simply unreasonable to put together a 1 hr talk to the climate deniers and expect them to “convert” just based on the merits of the evidence. Cause if it was that easy they would have already done so….right??We would not have a large swath of our county simultaneously holding conflicting beliefs. c) Finally the Confirmation Bias – we only seek information that confirms our beliefs.Also known as the consonance bias as it keeps our beliefs in harmony and does NOT allow any dissident information in.A few months ago I was speaking to a friend of mine, whom I first knew professionally and then became good friends.He was a computer programmer and a science major by training but deeply religious in his views.Generally applied to igneous rocks (those of volcanic origin), they measure the time since the molten rock solidified. Me – Well by that logic there are a couple of Indian Epics and Books (eg: Mahabharata and Vedas) that were written around the 1000 to 500 B. timeframe and reference events from more than 10,000 years ago that CAN ALSO be historically verified!If that happens to be longer than 10,000 years, then the idea of a young-Earth is called into question. But that is where I lost him and I became painfully aware that I could not make him change his position.
A method for determining the age of an object based on the concentration of a particular radioactive isotope contained within it.If that happens to be billions of years, then the young-Earth is in big trouble Him – well all that is fine but “you” do realize that the Bible says the earth was created 6000 years ago and we HAVE proof of the places referenced in the Bible. This got me thinking about beliefs and how people hold on to beliefs even in the face of overwhelming evidence.The Old Testament was written around the 6th century B. It could be the age of the earth; the age of the universe; climate change; evolution; superstitious belief; the healing power of prayer…it does not matter if you have the knockdown evidence or proof. Carol Tavris in her speech on “Why we believe – Long after we shouldn’t” attributes this to the DISSONANCE THEORY which has three major biases: a) The bias we are unbiased is we feel that we have no biases in our beliefs and that our beliefs are solidly grounded on facts.The latest high-tech equipment permits reliable results to be obtained even with microscopic samples.Radiometric dating is self-checking, because the data (after certain preliminary calculations are made) are fitted to a straight line (an "isochron") by means of standard linear regression methods of statistics.
Here is one example of an isochron, based on measurements of basaltic meteorites (in this case the resulting date is 4.4 billion years) [Basaltic1981, pg. Skeptics of old-earth geology make great hay of these examples.
