We often rely on other people’s advice for various types of decisions, whether at work, in games, or while deciding what smartphone to buy. More than just listening to other people, many of the decisions that affect our lives are made by a group or groups of people. If you are going out with your friends and want to pick a restaurant, you might create a WhatsApp group with all the invitees and try to pool the different opinions from everyone and reach a consensus. This also works for “bigger” decisions. Think for example of our political system: the amount…


Benjamin Franklin, réputé pour ses goûts littéraires raffinés, envoya un jour à un ennemi politique une lettre lui demandant s’il pouvait lui emprunter certains ouvrages de sa bibliothèque, dont « un livre très rare et très curieux ». Flatté, le rival lui fit parvenir le livre immédiatement. Franklin lui rendit les livres une semaine plus tard avec une note de remerciement. A l’assemblée suivante, l’homme approcha Franklin et lui parla en personne pour la première fois. …


Les erreurs de logique sont des formes de raisonnement fallacieux et peuvent être de deux types : les sophismes et les paralogismes. Ils se différencient par l’intention du locuteur : lors d’un sophisme, le locuteur a l’intention de tromper l’auditoire tandis que lors d’un paralogisme, le locuteur est de bonne foi. Dans cet article, on ne se placera pas en juges pour décider de l’intention des locuteurs, mais on illustrera cinq erreurs de logique par des exemples du premier débat pour l’élection présidentielle française de 2017.

tl;dr: If you’re debating with someone, it is always important to decide in advance, what proof or situation would be needed for either of you to change your mind. If no possible proof can ever do that, you wouldn’t be having a discussion, you’d be blindly arguing to prove a point.

In experimental science, when creating a research protocol for an experiment, we have to define a null hypothesis and then disprove it to prove the experimental hypothesis we are testing. This is closely linked to the notion of falsifiability as defined by Karl Popper. Falsifiability means that in order…


Why I argue online.

This was written by Albert on his blog and imported to Chiasma’s blog as it might be relevant to our readers.

Anyone who knows me will tell you that I like debating in general. I also argue online. A lot. I can stick with a Facebook or Reddit thread for days and one of my prime destinations on the web are forums to debate topics ranging from philosophy to politics, from dissecting a One Piece Manga chapter to arguing about the latest Hyperloop design.

Arguing online is different than arguing in “real time”. Arguing online has…

False Cause

“In Chicago, which has the toughest gun laws in the United States, probably you could say by far, they have more gun violence than any other city. So we have the toughest laws, and you have tremendous gun violence.” Donald Trump

Red Herring Fallacy

“Yes, I’m very embarrassed by it. I hate it. But it’s locker room talk, and it’s one of those things. I will knock the hell out of ISIS. We’re going to defeat ISIS. ISIS happened a number of years ago in a vacuum that was left because of bad judgment. And I will tell you, I will take care of ISIS.”
