1 - Start ~3 mins
You already know feeds are chosen for you by ranking systems. Today the question shifts to the content itself: when a post, advert or image leans on a ready-made idea about a group of people, can you spot it?
You will judge a set of invented digital examples for bias, then talk through what happens when the same stereotype shows up again and again.
2 - Examine and Discuss ~5 mins
Bias is when content leans toward one view, group or story and leaves others out or makes them look worse. A stereotype is a ready-made idea about a whole group (for example "all teenagers..." or "people from X always...") treated as if it were a fact about every person in that group.
Bias can sit in posts you already agree with.
Today's three verdicts:
- Balanced: fair enough about the people or views for what it is trying to do
- Shows bias: leans on a stereotype or one-sided frame in a way that matters
- Cannot tell from this: not enough detail yet to judge
Before the challenge: think of one stereotype you have seen online about people your age. Keep it to yourself for now.
3 - Hands-on: Bias Detective ~15 mins
Work through the bias detective interactive as a class. You may only do four examples fully as a class; two further items are there if time allows.
For each invented example, look at the tells, pick a verdict, then hear the reasoning.
- Read the example carefully (image description, advert, post or short report).
- Ask: who is shown, who is left out, and what ready-made idea about a group is doing the work?
- On your own (or with the person next to you), pick Balanced, Shows bias, or Cannot tell from this first — mini-whiteboard, scrap paper, or fingers-on-chest. Then vote as a class and hear the reveal.
- Listen to the reveal. Notice whether the lean matches a view you already hold. That is the hard part of the skill.
The examples cut both ways on purpose. Agreeing with a post does not make it balanced. One item is deliberately thin so Cannot tell from this can be the right call.

4 - How Stereotypes Shape Expectations ~8 mins
Now step back from single posts. Talk as a class about what repeated stereotypes can do over time.
Use these two prompts on the board. There is no single right answer the lesson is steering you toward.
- If the same kind of person is always missing from "clever", "brave" or "leader" roles in the media you see, what might that quietly teach viewers about who those roles are for?
- What is the difference between noticing a real pattern with evidence, and turning a pattern into a rule about every person in a group?
Quiet think (you do not have to say this out loud): pick one stereotype about teenagers that shows up a lot online. What expectation might it create for adults looking at you, and what expectation might it create inside your own head?
Stay analytical. Name the mechanism (repetition, who is shown, who is left out, jokes that harden into "common sense"). You do not have to agree with each other on how big the impact is.
5 - Make Sense ~4 mins
Pull the thread together.
- Bias is a lean you can name: who is centred, who is missing, what ready-made idea is doing the work.
- Stereotypes turn a pattern, a joke or a single story into a rule about a whole group.
- The skill is noticing the lean, whoever it favours, including in content you like as well as content you reject.
- Sometimes there is not enough on the screen yet; Cannot tell from this is a real verdict, not a cop-out.
- Repeated stereotypes can shape what people expect of others and of themselves, even when nobody meant harm in one single post.
You do not have to agree on how strong every impact is. You do need a habit of asking: who does this leave out, and what does it assume?
