When to use bullet points instead of paragraphs

Use bullets when your items are separate and equal, and use sentences when the ideas depend on each other. The shape you pick is a claim about the material. Bullets say these things stand alone, in any order. Paragraphs say this one caused that one.

Most bad work writing fails on shape before it ever fails on wording.

Bullets have become the house default because they look like effort with none of the deciding in them. That is my complaint with them, and it is not a style objection.

What a bullet list promises the reader

A list tells the reader the items are peers: same kind of thing, and none of them causing the others.

Readers act on that promise without thinking about it. They skip a bullet. They read the fourth one first. They come back a day later and pick up item two alone, with nothing else in their head.

That is skimming, and skimming is the default. A list is a promise you are making to somebody who has already started skipping.

When the promise is true, a list is generous. You have done the sorting so the reader does not have to hold the whole thing at once.

When the promise is false, you have handed them a puzzle with the picture removed.

What breaks when you bullet an argument

An argument in bullets loses the words that were doing the work: because, so, unless, which means, and therefore we should.

Those joining words are the argument. Take them out and you have claims parked next to each other, and the reader has to guess how they connect.

Here is a real shape I have both sent and received. Three bullets: the vendor missed their date, the testing window is now shorter, launch is at risk. All true. All useless.

The sentence version says something the bullets refused to: the vendor missed their date, so testing lost a week, and unless we drop the import screen the launch moves.

Same facts. One version names a consequence and a choice. The other version is what people send when they do not want to be the person who said the launch will move.

I am fairly sure that is the main reason work writing gets bulleted. Bullets let you report a problem while staying quiet about what follows from it. Call that what it is: deniability with white space around it.

The material that really belongs in a list

List material is anything a reader handles item by item, and can put down between items.

• Options that are true alternatives, where choosing one rules out the others.
• Steps that must happen in a fixed order, numbered so people can argue about step three.
• Reference material the reader will scan again later instead of reading once.
• Separate tasks that land on different people and can be done in any order.

Reasoning fails that test every time. So does anything you would say out loud with a "because" sitting in the middle of it.

The tell is simple. If you would speak it as one breath, it is a sentence.

Numbered, bulleted, or neither

Numbers mean order or reference, bullets mean neither, and a lot of lists should be a sentence.

Number the list when the reader has to do the items in sequence, or when you want a reply that says "on 2, I disagree". Numbers give people handles. A thread where everyone can point at item four without quoting it is a faster thread.

Bullet the list when order genuinely does not matter, and then check that claim by reading the list backwards. If it reads worse backwards, it was never a bullet list.

Use neither when you have two items. A two-item list is a sentence with extra whitespace, and it makes a small message look like a form.

Nine items is also not a list. Past some length the eye stops reading a list and starts treating it as texture, which makes a long list a quiet way of hiding the things at the bottom of it. If you have nine, you have a document, or you have three things with six details attached.

The shape most work messages actually want

Most messages want one sentence carrying the point, a short list of the parts, then one sentence saying what happens next.

The reason is that a naked list makes no claim. Somebody has to say what the list means, and if you do not, the reader will pick a meaning for you, usually the one that costs them the least.

So the opening sentence commits: we can still hit the date if we cut one thing. Then the list does what it is good at: the three candidates for cutting. Then the closing sentence commits again: I would cut the import screen, tell me by Thursday if you would not.

That last line is where these messages usually collapse. The list gets written, the ask never does, and the thread turns into a week of people admiring the options. If there is a decision inside your message, say plainly that you are asking for one.

How to unbullet something you already wrote

Read your list aloud and try to slip "because" or "so" between the items. If it fits, you wrote a paragraph in disguise.

• If reordering the bullets changes the meaning, the material has an order and wants sentences.
• If every bullet starts with the same verb form only because you forced it, the shape is fighting the content.
• If a bullet has bullets under it, you are looking at an outline you wrote for yourself, not a message for them.
• If one bullet is three lines long and the rest are four words, the long one is the actual message.

That last case is the common one, and the fix is to promote the long bullet to the first sentence and delete about half of what remains.

I do that by hand when there are five minutes left in me. When there are not, I type the bulleted version straight into the reply and take the Polished rewrite from Unvent, which puts the joins back where I left them out.

Watch what happens the next time someone puts a bulleted slide on the screen. They read the bullets, and then they say the joins out loud: this happened, so we did that, which means we need a call on the third one. Those spoken sentences were the message the whole time. The bullets are the part that got typed.
