Teach judgement, not buttons
In this lesson you will:
- Design training around judgement and checking rather than interface steps
- Use people's own real work as the material, in short sessions with practice
When a team gets a new tool, the instinct is to train people on the tool: where to click, which menu, what the button does. It feels concrete and it is the least durable thing you can teach.
Lrnon’s whole curriculum rests on the opposite belief: that the lasting skill is judgement, and that tools are the part that changes.
Why buttons expire
Interfaces change continually. A set of screenshots is wrong within weeks. A session spent on where things are is spent on knowledge with a half-life shorter than the session’s afterglow.
It also teaches the wrong relationship. A person who learns the tool as a sequence of steps follows the sequence, and does not notice when the output is wrong, because noticing was never part of the lesson.
What lasts
Three things stay useful across tools, versions and vendors.
How to check the output
The single most valuable habit. Explorer’s E7 is the full treatment; for a rollout, the essentials are:
Treat fluency as no evidence. A confident, well-written answer can be wrong.
Know which claims need checking: numbers, names, dates, quotations, anything that will be relied on or sent to someone else.
Check against something independent, not by asking the tool whether it is sure.
Know what a check costs, and when it is worth paying.
A team that has only this has most of what matters.
What must never go in
Concrete, specific, and tied to their data. Not “be careful with personal information” but “customer names, email addresses, account numbers and anything from the HR folder do not get pasted into this tool, and here is what to do instead”.
P8 explains why: the provider is a recipient, its terms differ by plan, and what you send leaves your control. For a team the useful form is a short list of examples, because people reason from cases better than from principles.
When it is likely to be wrong
Some situations raise the chance of a confident error: obscure facts, recent events, specific figures, long or unusual documents, and anything where the tool has to know something it was not given. A person who can say “this is the kind of question where it tends to make things up” will check at the right moments.
Teach with their own work
Generic examples teach generic skills. People remember what they did with their own material.
Use real tasks. Have each person bring something they need to do this week and do it during the session. It converts training time into work time, which is also the best argument for attending.
Include a failure on purpose. Show a case where the tool gets something wrong in a way that looks right, drawn from the team’s own area if you can find one. Seeing it fail is more persuasive than being told it can.
Let them break it. A safe space to try odd requests and see what happens teaches limits faster than a list.
Short, repeated, soon
How long and how often matters more than most people expect.
Short sessions. Forty-five minutes to an hour, with a task to do. A day-long workshop is mostly forgotten by the following week.
Practice inside the session, not just demonstration. People retain what their hands did.
A reminder soon after. A follow-up in a week or two, asking what they tried and what went wrong. It is the point where the habit either forms or lapses.
Written notes on one page. Not a manual. The few things to remember, and where to ask.
Make it safe to say “I don’t know”
A team where everyone pretends to understand the tool is a team making unreported mistakes.
Say openly that nobody has this fully worked out, including you. Treat errors found by checking as the system working and not as someone’s failing. If a person catches the tool being wrong, the right response is thanks.
This matters for the quality of what you learn as well. Mistakes people are afraid to admit never reach you, and you cannot fix what you cannot see.
How Lrnon does it
The platform’s curriculum is built on this premise: it teaches judgement, not tools. It names real products because avoiding them would make the teaching abstract, shows the source and date for every description so a reader can check, and returns again and again to verification, what not to hand over, and when to stop.
That is why most of it will still read correctly when the products have changed. A lesson on checking a claim in two minutes does not depend on any vendor’s menu. A lesson on where to click in a particular app would need rewriting each season.
Try it now (15 minutes)
Outline a session for a team. Write the three things you want them to leave with, and for each, one exercise using their own real work.
Then check the outline for any slide that is a screenshot of an interface. For each one, ask what you could teach instead that would still be true in a year.
Check your understanding
Recap
Teach what lasts: how to check output, what must never be pasted in, and when the tool is likely to be wrong. Tool-specific click paths expire quickly and teach people to follow steps rather than notice errors. Use each person’s own real work, include a deliberate failure, keep sessions short with practice inside them, and follow up within a couple of weeks. Make it safe to say you do not know, since mistakes people fear to admit never reach you. Lrnon’s curriculum is built on this premise.
