@JulienDelpierre this is a wonderful graphic. I wonder how humans, primates and crows would place in this chart
@JulienDelpierre yes, agree. Additionally, it is limited by out framing. I think it is unfortunate that the unknowns make it seem like they are “not evident”. Without taking the time to truly understand the graphic it seems that pigs are clearly have more that other animals… but the true interpretation is only that we can perceive pigs intelligence in those areas. There is a stark absence of “not likely”
@timjohnclarke A limit to this kind of study is that we take ourselves as a reference. In other words, humans would check all the boxes. For crows and primates would most definitely score very high!
