The Hidden Rules of Conversation

Gricean Maxims are a vital part of how we understand each other: a set of... well, maybe "rules" is a bit strong. They're guidelines that we follow without realising it. And it's the reason that "asbestos-free cereal" sounds suspicious.

    I've been a math student a few years and we learned to be very precised in our words for demonstrations. We had to prove something was an absolute TRUTH or wasn't. This comment section really reminds me when we overstep it in our real conversations. "That's what this product is made of, you know." "Well, no, I don't know." "You're playing with words... " It still happens. And I'm genuinely thinking my interlocutor think I have to already know for sure the given information. 😅

    Tomatoes have been genetically modified to incorporate fish genes, IIRC to boost the plants' resilience to near-freezing temperatures. Some vegans might not take issue with this as the produced organisms would continue to be free of a central nervous system, but most would trace those genes back to their aquatic ancestor's lab death and take issue. Actually, I'm assuming the 'donor fish' didn't have its DNA harvested delicately, but either way most vegans would take issue.

    The 'Low in sugar' bit isn't honest, it's a straight out lie unless it's proven to be low in sugar according to a certain standard. That's like saying Tic-Tacs are 'sugar free' despite them being pure sugar, simply because one mint is a single serving and weighs less than a gram, and the standard definition of 'sugar free' is to have less than 1g per serving of sugar.

    because I grew up with a mental disorder that delayed my language development, I became a naturalist when it came to flouting. However, I do it unintentionally because of how my brain is wired, and that causes me to associate some concepts slightly differently. it's quite sad when you think about it, however, as I grow up I slowly amend these associations to their correct meanings even though this natural process likes to take its time. life is harder for someone like me.
