Two chairs are pulled close to one monitor, and the cursor stops moving for a few seconds. One person is thinking through the edge case. The other is looking at the test name and quietly asking whether it describes the behavior or only the implementation. Outside the pair, it may look slow. Inside the pair, a small mistake has just been avoided before it became a pull request comment.
Pair programming creates strong opinions because it changes the feeling of work. Some engineers love the shared focus. Some find it tiring, exposed, or inefficient. Both reactions can be honest. Pairing is not automatically a mature practice, and refusing to pair is not automatically a sign of poor collaboration. It is a tool. Like most tools, it works best when the team understands the job it is being hired to do.
At its best, pairing shortens feedback. Instead of writing code alone for two days, opening a PR, waiting for review, and then discovering a mistaken assumption, the assumption is challenged while the code is still soft. The second person notices naming, missing tests, unclear domain language, risky shortcuts, or a simpler path. The review happens continuously, not as a gate at the end.
Pairing is especially useful when the problem is ambiguous or expensive to get wrong. A payment flow, a migration, a security-sensitive change, a strange production bug, or a piece of code nobody fully owns may deserve two minds at the same keyboard. One person can drive the change while the other holds the wider map: what are we assuming, which test proves it, what might break, where should we stop?
It also helps with onboarding. A new teammate can learn more from one calm pairing session than from hours of reading stale documentation. They see how the team names things, runs tests, navigates the codebase, talks about trade-offs, and recovers from mistakes. The value is not only the code written during the session. It is the transfer of taste and context that would otherwise take weeks to infer.
But pairing can become heavy when used without judgment. Pairing all day, every day, on every task can drain people who need quiet time to think. It can turn small changes into meetings. It can hide unequal participation, especially when one person dominates the keyboard or the conversation. It can make junior engineers feel watched instead of supported. It can make senior engineers feel unable to enter deep focus. A practice meant to improve collaboration can become another source of fatigue.
The simplest fix is to make pairing intentional. Do not ask whether the team believes in pair programming as an identity. Ask which tasks deserve it. Pair on confusing bugs, risky changes, new domains, architectural decisions, and learning moments. Work solo on straightforward implementation, mechanical refactors, small copy changes, and tasks where uninterrupted focus matters more than immediate discussion. The point is not to maximize pairing hours. The point is to put shared attention where it pays.
Good pairing also needs roles. In the classic model, the driver types and thinks locally while the navigator watches the direction, asks questions, and keeps the larger goal visible. In practice, the roles should switch often enough that both people stay engaged. If one person drives for the whole session while the other slowly becomes a spectator, the pair is losing half its value. A small timer can help, not because rules are sacred, but because rotation prevents the session from settling into hierarchy.
Psychological safety matters here. The best pairs speak in small, non-threatening observations: what behavior are we proving, what happens if this returns null, could this name be clearer, should we write the failing test first? The worst pairs turn every suggestion into a judgment. Pairing puts thought in public before it is polished. That can be generous and useful, but only if both people treat unfinished thinking with care.
Remote pairing adds another layer. Screen sharing, editor sharing, audio lag, and notification noise can make a session tiring. Shorter sessions usually work better. So does a clear goal at the start and a short note at the end: what changed, what remains, what decision was made. Without that, remote pairing can feel like a long call where code happens incidentally. With structure, it can be one of the fastest ways to unblock a distributed team.
I like pairing most as a temporary concentration of trust. For one hour, two people agree to put their attention on the same problem and make each other better. Then they separate and continue with more shared context than before. That rhythm respects both collaboration and solitude. Software needs both.
So, love it or hate it? Maybe the better question is: what kind of work are we doing right now? If the answer is risky, unclear, new, or important to share, pairing may be the quiet tool that saves time later. If the answer is routine and well understood, solo work may be kinder. The maturity is not in choosing one forever. It is in knowing when another chair beside the keyboard would actually help.
