Sure, confirmation bias refers to a poor way to argue. If research is done with a confirmation bias then it's very likely the research could reach incorrect conclusions. Say, we wanted to argue about a dog named Harvey.
Let's say that we want to argue that
Harvey is a good boy.
Is it a true statement that "Harvey is a good boy"?
Someone produces a report and argues Harvey is a good boy because:
- Harvey fetched a stick
- Harvey loves his people
- Harvey gets treats for being a good boy
- Harvey does tricks
- Harvey does not chase cars
Therefore we conclude Harvey is a good boy.
However, last month, Harvey tore up a very expensive couch. Harvey's people have to be careful how close they let Harvey to a couch because Harvey will destroy the couch. So, we could also argue "Harvey is a bad boy."
Conformation bias happens when we only present facts that support the case, and we don't seek out or ignore facts that are contrary to the claim.
A more complete report might conclude "Harvey is often a good boy, but we should keep him away from couches."
