       | Instead the article and even recent 'scientific' papers now start
       | with the outlandish conjectures by the author based on some
       | strained potential interpretation of the evidence.

         | This is a typical problem with Quanta. I'm not quite sure who
         | their target audience is, but I doubt they get anything beyond
         | the vaguest idea of what is done here. And if you know more,
         | you don't need to be told about Thomas Bayes etc. and you could
         | probably quickly realize that the research is an
         | overinterpreted incremental thing dressed up as a breakthrough
         | to advance careers and back-scratch some famous academics who
         | then go on to pose as the face of, and to take credit for an
         | entire subfield/line of research.
         | 
         | Laypeople would gain much more from learning about solid,
         | settled and stable pieces of knowledge about various scientific
         | aspects. Instead, we get these weird frankenstein stories
         | mixing basic concepts and cutting edge research, where in the
         | end readers go aways with a smug sense of satisfaction of
         | keeping up with new scientific developments while not really
         | understanding what it really was about.
         | 
         | Instead, listening to a well-structured didactic lecture or
         | reading a textbook has much better "return on investment", but
         | it's less satisfying than the glossy magazine (or its online
         | equivalent).

           | No one knows how human memories are stored, it's ridiculous
           | to assert that quantum noise plays a role when we can't even
           | tell whether it's the brain's connectome that stores memories
           | vs. molecules like talin.

       | reputation for being bad at probability?
       | 
       | Maybe we are able to grasp probabilities at the most fundamental
       | parts of our physiology, but layers and layers of cognition on
       | top of it add estimators with noise (all our guesses around the
       | world and ourselves) which pretty much hide entirely the
       | probabilistic foundation (perhaps due to limits in cognition &
       | memory degradation). Guessing that something is "a red car
       | turning left" is a hell of a lot more complicated than guessing
       | whether a singular line is at a 45-degree angle. For the latter
       | maybe we can tap into neuronal activity almost 1-to-1, for the
       | former you have to add estimators around red, car, turning, left,
       | and language assumptions.

       | cannabinoids and our brains have more cannabinoid receptors than
       | any other kind (stuggling to find a source for this atm, I read
       | it somewhere on the internet)
