  • Selection bias.
  • Observation bias (also known as the Hawthorne Effect)
  • Confirmation bias.
  • Publishing bias.

Is bias inevitable in science?

But while biased scientists are inevitable, biased results are not, as illustrated by Morton ( biased ) and his data (unbiased, as far as we can tell). Science does not depend on unbiased investigators but on methods which limit the ability of the investigator’s bias to influence the results.

Why is it important to recognize bias in science?

It’s important to understand bias when you are researching because it helps you see the purpose of a text, whether it’s a piece of writing, a painting, a photograph – anything. You need to be able to identify bias in every source you use.
