it wasn’t a convincing article even for someone who agrees with the researcher/author 🤷

We trained one group of bees to associate the color blue with a sugary reward and green with no reward, and another group of bees to make the opposite association. We then presented the bees with a turquoise color, a shade intermediate between blue and green. A lucky subset of bees received a surprise sugar treat right before seeing the turquoise color; the other bees did not. The bees’ response to the ambiguous stimulus depended on whether they received a treat before the test: those that got the pretest sugar approached the intermediate color faster than those that didn’t.

The results indicate that when the bees were surprised with a reward, they experienced an optimistic state of mind. This state, which was found to be related to the neurotransmitter dopamine, made the bees more upbeat, if you will, about ambiguous stimuli—they approached it as they would the blue or green colors they were trained to associate with a reward. It also made them more resilient toward aversive stimuli, as occurs in humans: bees that were given a surprise dose of sugar recovered faster when ambushed by a fake predator, taking less time to reinitiate foraging than their peers that did not receive sugar before the simulated attack.

might the researcher’s mind be in a too optimistic state to jump to conclusions? They probably received sugar before the experiments :)

I’ve never understood the absurd mindset of “we’re animals and we feel emotions and pain, so clearly other animals don’t feel those things.” The entire idea is incredibly stupid and irrational both on the surface and with even the smallest shred of scrutiny by anyone who has observed literally any animal for any amount of time.
