Can’t tell you how much

An app about dishonesty in conversation and it can’t be honest about how much, ironic?

Excellent Concept, But Somewhat Biased

Really good app and a great way to learn about logical fallacies. My only issue is that some of the examples and arguments feel a little politically biased, leaning more towards the left rather than taking a neutral or centrist approach. At times, the selection of examples feels like cherry-picking, and I’d love to see more balanced examples from different perspectives. That said, overall it’s a very nice app and I’ve enjoyed using it.

恶心死了

Deutscher Nutzer hier :)

Hab die App über Reddit gefunden und mal ausprobiert, funktioniert echt gut und macht Spaß. Sie hilft spielerisch in der heutigen Zeit zu erkennen was wirklich News, Übertreibungen oder sowas sind. Oder wenn man versucht unseren Verstand mit Methode XYZ zu beeinflussen.

Man wird halt auf den ein oder anderen Mind-Trick vorbereitet.

Ich find die App cool und lass mal 5* da.

Response from developer

Danke — und schön, dass der Umweg über Reddit sich gelohnt hat. Genau darum geht es: die Mind-Tricks zu erkennen, bevor sie wirken. Freut uns, dass das nebenbei auch noch Spaß macht. — das Fallacy-Team
