Qualifiers and Caveats. Don't squander the opportunity to write forcefully by beginning with secondary points and caveats. They belong in the body of the paragraph or section, but not as openers. Distinguish between strong and weak statements. Good scientific writing uses qualifiers and caveats sparingly.
Qualifiers apply to marginal results, arguable statements, speculations, and potential artifacts.
They do not apply to strong findings, well-confirmed statements, or bedrock theory. They are not to be used reflexively. Electric shock, however, increased hunger two-fold. It also appears that water-deprivation seems to lower hunger. Big words and long sentences.
