Well, the very power of the scientific method *is* that they can
  "change their mind tomorrow" so to speak. Facts-as-facts are
  necessary in school but beyond school, less so. Within the
  disciplines of the sciences, the variability in research
  findings is a bonus. I love Google Scholar and live in it
  sometimes. I'm not looking for hard facts because I don't have
  to: I have no tests to pass and no newspaper headlines to write.
  But what I'm looking for is a broad comprehension of the
  strengths and limitations of each field, of each study, and
  somewhere within the mix, come up with some plausible reasoning
  to support whatever is necessary for me at the time, but all the
  while knowing (gratefully so!) that the concept I'm leaning on
  could vanish tomorrow, which keeps me nimble and alert and
  looking for the deeper strengths within each, rather than
  following the latest finding. "New study shows....[insert
  something that overturns 'everything we knew before] has to be
  taken with great skepticism. == The power is that both efforts
  take place simultaneously. == You may be seeing an either/or
  situation.* I'm speaking "both/and". == The various disciplines
  of the sciences (there are many disciplines, many sciences) are
  each viewing the world from their own point of view. Biology
  sees what it sees and interprets through its lens. Physics sees
  what it sees and interprets through its lens. Psychology sees
  what it sees and interprets through its lens. Yet, none of them
  have a singular lens in their own disciplines. There are
  different opinions that vary TREMENDOUSLY within each
  discipline. I'm friends with several theoretical physicists, as
  well as a few going to school for it. They can fight like cats
  and dogs over some things. Within psychology there's just as
  much variety. Pick a discipline with a theoretical component to
  it, and you'll find heated debates about nearly everything. One
  exception MIGHT be chemistry, although there _is_ a limited
  theoretical chemistry field out there, but it doesn't have a
  strong voice because chemistry-as-is is extremely reliable and
  powerful as it stands. Now, what's a general consensus among
  scientists within a discipline? Which scientists? Which studies?
  Who is using the studies and for what purpose? These are all
  important and the facts necessary to use can change with the
  needs of the user. This doesn't invalidate any of it. But,
  outside of chemistry, I can't think of any field that isn't
  bustling with opinion, debate, argument in some fashion. Yet at
  the same time, some things appear to be sturdy and reliable.
  Those are facts. They're practical. Science is a pragmatic
  field. Use what works. Maybe next year something will work
  better. Today's "This is the answer to why?" might not be as
  effective as the answer in 10 years, 100 years. General
  consensus is more of a wibbly wobbly thing. That's what makes it
  powerful. Science can change. Yet when you find a general
  consensus of sorts that's strong enough to support what you need
  it for at the time, the chain of evidence is usually strong
  enough to be pragmatic for its purposes. Science isn't scripture
  nor is it law. It's its own thing. == Science is mitigated
  certainties. It works. It is akin to a rope bridge. Do you trust
  enough to cross? You apply what you know using the methodology
  of proof that seems to work well and you cross. Can I build a
  skyscraper on it? Probably not. But it is strong enough to
  cross, good for its purposes. I apply the scientific method to
  nearly everything yet not exclusively so either. It's more akin
  to the engineering method [I have a chart somewhere that shows
  the differences between them]. The methodology you're learning
  is sound. My point is: it's not a weapon. ==
