Human Bias

This note collects evidence demonstrating the need for self-governance of all agents, including nonhuman beings.

Cf.

  • speciesism: prioritising human interests over those of other species
  • anthropocentrism: viewing humans as the central or most significant entities
  • geographic bias: favouring certain regions (e.g., developed over remote)
  • taxonomic bias: focusing on specific taxonomic groups (e.g., vertebrates over invertebrates)
  • citation bias: preferentially citing already prominent studies, studies in certain disciplines or languages, or studies from certain regions or authors
  • size bias: favouring larger species over smaller ones
  • land over ocean bias: prioritising terrestrial ecosystems
  • charismatic species bias: focusing on aesthetically appealing or "charismatic" species
  • evolutionary bias: favouring species closer to humans in evolutionary terms
  • temperate over tropical bias: prioritising temperate ecosystems over tropical ones
  • plant blindness: overlooking the importance of plants in ecosystems
  • mineral or resource bias: prioritising human use of non-living resources over their intrinsic or ecological value
  • ecological bias: undervaluing the roles of less visible or less understood organisms

Examples of Bias in Life Sciences

Preference for charismatic species

Colléony, Agathe, Susan Clayton, Denis Couvet, Michel Saint Jalme, and Anne-Caroline Prévot. ‘Human Preferences for Species Conservation: Animal Charisma Trumps Endangered Status’. Biological Conservation 206 (2017): 263–69. https://doi.org/10/f9wz8q.

But being charismatic does not help as humans end up thinking there are a lot of you.

Preference for larger body

Preference for closer evolutionary relatives

Miralles, Aurélien, Michel Raymond, and Guillaume Lecointre. ‘Empathy and Compassion Toward Other Species Decrease with Evolutionary Divergence Time’. Scientific Reports 9, no. 1 (2019): 19555. https://doi.org/10/ggp7t9.

Thomas, Howard, Helen Ougham, and Dawn Sanders. ‘Plant Blindness and Sustainability’. International Journal of Sustainability in Higher Education 23, no. 1 (2021): 41–57. https://doi.org/10/gjq9ts.

In Europe, funding for conservation between 1992 and 2018 through LIFE projects was:

  • 150 million for invertebrates
  • 970 million for vertebrates

Mammola, Stefano, Nicoletta Riccardi, Vincent Prié, Ricardo Correia, Pedro Cardoso, Manuel Lopes-Lima, and Ronaldo Sousa. ‘Towards a Taxonomically Unbiased European Union Biodiversity Strategy for 2030’. Proceedings of the Royal Society B: Biological Sciences 287, no. 1940 (2020): 20202166. https://doi.org/10/gjfxkt.

This bias is contrary to the extinction risk: 26.3% of invertebrates are critically endangered, endangered or vulnerable vs 13.3% of vertebrates. (see IUCN Red List)

Preference to temperate over tropical
