- [2](https://md.mova.elamur.ai/free/en/corpora/school/world/165-the-brother-who-never-does-anything-wrong-double-standards/2/) — A double standard is judging the same thing differently depending on who did it.

- [4](https://md.mova.elamur.ai/free/en/corpora/school/world/165-the-brother-who-never-does-anything-wrong-double-standards/4/) — Special pleading is a rule for everyone except me: "No phones at the table," says Dad, then checks his own: "That's different, it's work." Or: "Sugar is bad," says Dad, eating a doughnut, "but grown-ups need energy."
- [5](https://md.mova.elamur.ai/free/en/corpora/school/world/165-the-brother-who-never-does-anything-wrong-double-standards/5/) — Watch out for "always" and "never".

- [7](https://md.mova.elamur.ai/free/en/corpora/school/world/165-the-brother-who-never-does-anything-wrong-double-standards/7/) — Count first, then speak: "You were late today" is fair and true.
- [8](https://md.mova.elamur.ai/free/en/corpora/school/world/165-the-brother-who-never-does-anything-wrong-double-standards/8/) — The mockery aims at the unfairness, not the person: "Oh, the invisible sheet.
- [9](https://md.mova.elamur.ai/free/en/corpora/school/world/165-the-brother-who-never-does-anything-wrong-double-standards/9/) — The famous invisible sheet." A fair rule is one that would still sound fair if you swapped the names.
- [10](https://md.mova.elamur.ai/free/en/corpora/school/world/165-the-brother-who-never-does-anything-wrong-double-standards/10/) — A double standard means judging the same act or result differently depending on who did it.
- [11](https://md.mova.elamur.ai/free/en/corpora/school/world/165-the-brother-who-never-does-anything-wrong-double-standards/11/) — Special pleading means making an exception to a rule for yourself or a favourite without a real reason.
- [12](https://md.mova.elamur.ai/free/en/corpora/school/world/165-the-brother-who-never-does-anything-wrong-double-standards/12/) — The swap test: if a rule or judgement stops sounding fair when you swap the names, it is a double standard.

- [14](https://md.mova.elamur.ai/free/en/corpora/school/world/165-the-brother-who-never-does-anything-wrong-double-standards/14/) — Calling every example that breaks your rule "an exception" is a trap; grown-ups call it "no true Scotsman".
- [15](https://md.mova.elamur.ai/free/en/corpora/school/world/165-the-brother-who-never-does-anything-wrong-double-standards/15/) — "Always" and "never" are almost never true about people; count the times before using them.
- [16](https://md.mova.elamur.ai/free/en/corpora/school/world/165-the-brother-who-never-does-anything-wrong-double-standards/16/) — Age can be a fair reason to be gentle, but then it must be fair for every child at that age.
- [17](https://md.mova.elamur.ai/free/en/corpora/school/world/165-the-brother-who-never-does-anything-wrong-double-standards/17/) — If a rule has a good reason, like talking together at dinner, it applies to everyone; a real exception, like an emergency, should be said in advance for everyone.

- [20](https://md.mova.elamur.ai/free/en/corpora/school/world/165-the-brother-who-never-does-anything-wrong-double-standards/20/) — Same mark, same praise: effort can be talked about separately and honestly.
- [21](https://md.mova.elamur.ai/free/en/corpora/school/world/165-the-brother-who-never-does-anything-wrong-double-standards/21/) — Words people use: "make it make sense" means this makes no sense (young slang), "sit down" means you're in no position to judge, "doughnut man" is a jokey nickname, "The Chase" is a TV quiz show in Britain, "wanna" means want to, and "bossy" here is a joke about gum giving orders.
