An “erroneous” conclusion can also be reasonable? How so?
Most opinions or beliefs are based on information that is incomplete. Otherwise, they’d be axe-through-the-skull certainties. When information is incomplete, there is often more than one reasonable way to interpret the information. In many cases, only one interpretation is correct, but the available information itself does not compel a particular interpretation and render others irrational.
This is college-freshman stuff, whether you’re taking Philosophy 101, Basic Logic, or Intro to Communications.
