Living in a ‘post-fact’ world

“Once the trained CNN [convolutional neural network] showed solid performance in the simulator, we loaded it onto DRIVE PX [vehicle control computer] and took it out for a road test in the car. The vehicle drove along paved and unpaved roads with and without lane markings, and handled a wide range of weather conditions. As more training data was gathered, performance continually improved. The car even flawlessly cruised the Garden State Parkway.”

Studies find that people with higher numeracy and understanding of the scientific method and its tools are more likely to challenge or twist the results of scientific studies that challenge their ideologies. For example, it’s the more scientifically competent persons on the political right (those who are most identified with a free-market ideology) who mount the most vehement assaults against claims of human contributions to global warming.

This article delves into the extent of cognitive biases against facts (rigorously validated knowledge claims) and the apparent variables affecting when those biases are triggered. It also raises possible ways to mitigate biases.
