What is problematic about being swayed by a good story?

A good story may not be supported by data

How are basic and applied research different?

Basic research is research of basic info. Applied research take a basic research and created new development, tech research is creating new product with the info from basic and applied

Name and describe the kinds of biases of intuition discussed in the text

Being swayed by a good story: Accepting a conclusion just because it makes sense or feels natural. Being persuaded by what comes easily to mind: Availability heuristic. Things that pop up easily in our mind tend to guide our thinking. Failing to think about what we cannot see: People forget to think about the information that is not put in front of them. Focusing on the evidence we like best: Confirmation bias, Seeking and accepting only the evidence that supports what we already think. Biased about being biased: The belief that we are unlikely to fall prey to the other biases previously described
