Episode notes

Delve into the fascinating world of insect welfare, exploring their complex behaviors and capabilities beyond common perceptions. The chapter challenges assumptions about insect sentience, drawing parallels to known sentient animals and discussing the evidence for insect pain experiences. The conversation invites reflection on biases, empathy, and the importance of considering insect welfare despite their size or perceived intelligence.

Bob Fischer is the Senior Research Manager at Rethink Priorities and Associate Professor of Philosophy at Texas State University.

Can insects feel pain? Should people who care about chickens, cows and pigs also care about reducing the suffering of crickets or black soldier flies? In this episode with Bob Fischer from Rethink Priorities, we try to answer some of those questions, as well as talking about the rapidly growing insect industry, and possible ways for advocates to help farmed insects.

We talk about lots of interesting content and research, for some of which there are excellent visualisations, which we’ll link to at the top of the show notes. I highly recommend checking out the Welfare Range Table and Rethink Priorities’ Welfare Range estimates to help better understand some of the points here, both of which are linked.

Bob also had a great conversation on the 80,000 Hours Podcast about the moral weights project more broadly and how they want to try to compare welfare across different species of animals. We think they covered it very well, so we didn’t speak much about it today, so we’ll link it for interested folks.

Research paper, “Can Insects Feel Pain?”, which found that two orders of insects (which include cockroaches, termites, flies and mosquitos) met more criteria to feel pain than decapod crustaceans (e.g. crabs, lobsters, shrimp), which are recognised as sentient by the UK government.
