There is plenty of advice telling you to drop modifiers such as “I think” from your speech and writing. There is virtually no one telling you to do the opposite, which is a shame, since modifiers are quite useful for communicating.

While it’s true that some people could be more confident in general, “have more confidence” isn’t good advice. People will assume that they should have more confidence in their least confident moments, so they lose out on the most important thing: the range of confidence levels expressed. The actual values do not matter so much, just how they compare relative to each other. For instance, when a scientist says “we have not found any evidence supporting X,” we understand that they mean “we are very confident X is untrue” because they have different ways of saying “we have no idea what’s going on.”

There’s also a semantic effect that modifiers have on your writing. If in the first paragraph I said “…since modifiers are useful for communicating,” you’d assume — without further context — that what came before is something of the form “People use modifiers often”. But if I say “…since modifiers are quite useful for communicating” it implies that what came before happened in spite of this fact. And that is why, in the first paragraph, I introduced that modifier where I did.

Besides the obvious function of modifying a statement, modifiers have another use: pacing. When you say “I think” or “maybe” it weakens the statement. When you omit modifiers and pointedly deliver a line, you emphasize it. But why would you want to express weakness in your argument? Because it helps you communicate clearly. What do you think, and what do you know? What’s concrete advice, and what’s just a potential option?

If an honest writer drops the modifiers in their writing, just like their teachers tell them to, they typically also drop its nuances. Any essay consisting only of absolute, unqualified truths is not worth reading. It’s not even worth writing. That’s why every high school English paper looks like it was written by an elementary schooler. It’s not because the author is a dunce. It’s because they don’t allow themselves to say anything a dunce doesn’t already know.

Any advice telling you to discard a tool that creates variety is almost always wrong. You might not think removing modifiers would change the substance of your writing. But if you want to write better, you have to change the way you write. Or in this case, you have to stop letting your English teacher change the way you write. Sometimes a modifier might not seem to convey any additional information. But modifiers aren’t just a matter of practicality, they’re a matter of style.

And I think it makes for damn good style.
