How to compare several products with someone without losing the thread

Why group chats are bad at shortlists, and what to do instead when three people are choosing between eight things.

  1. Put every candidate in one place first

    Before anybody gives an opinion, get all the options onto a single page. A decision made across three chat threads is really three separate decisions, and the person who joins last has no idea what has already been rejected.

  2. Let each person react on the item itself

    A thumbs-up on a product is a vote that stays attached to that product. In a chat, "this one!" refers to whichever link was most recently pasted, which stops being true the moment somebody pastes another.

    A shelf on a phone: a single column of product cards, each with a row of reaction buttons underneath.
    Reactions sit on the product, so a vote still means something a week later.

  3. Use notes for the reason, not just the verdict

    "Nice but the sleeves" is worth more than a thumbs-down, because it tells you what to look for next. A shortlist where every rejection carries a reason turns into a brief for the next round of searching.

  4. Narrow by removing, not by re-listing

    Delete what is out rather than starting a new list of what is in. A shelf that shrinks keeps its history — you can still see what was there — where a fresh list every round loses everything anybody said.

Why the group chat loses

A chat is ordered by time; a shortlist is ordered by preference. Every message pushes the options further apart, so by the twentieth message the first candidate is a scroll away and effectively gone from the conversation.

It is also lossy in one direction only: opinions survive, the things they were about do not. Two weeks later you have "I liked the second one" and no way to work out which that was.

The third problem is quieter and worse. Anyone who joins late — the friend you add on Thursday, the parent who finally opens their phone — arrives at the bottom of a hundred messages with no way to catch up. In practice they either re-suggest something already rejected, or stay silent, and both mean you have lost an opinion you wanted.

When to stop collecting

Shortlists fail more often from being too long than too short. Past about eight candidates people stop comparing and start skimming, and the decision gets made by whatever was seen last rather than by what was best.

A reasonable rule: when a new option arrives and nobody can say what it beats, you are finished collecting and should start removing. The list has become a search result rather than a shortlist.
