There’s a hidden bias affecting what we know – and don’t know – about nature
What drives scientists to uncover nature’s mysteries is curiosity. But what are they curious about?
Scientists studying life on Earth face a hidden bias that influences which species they focus on. With millions of species on the planet, it's impractical for researchers to investigate every single one. Instead, scientists choose which animals to study based on their own curiosity and past experiences. Unfortunately, this often leads to an unfair representation of certain species in research.
Our analysis of nearly 1.4 million scientific articles reveals a strong bias towards studying vertebrates, such as birds, mammals, and reptiles. These animals make up only 5% of all animal species but dominate the majority of research. In contrast, invertebrates, which include insects, spiders, worms, and mollusks, comprise the vast majority of species, yet receive far less attention in scientific literature.
The bias persists despite efforts to improve it over the past two decades. Factors contributing to this bias include popular media and public interest in charismatic animals, which often overshadow less glamorous creatures. Social media and news coverage often focus on animals that are seen as cute or interesting, inadvertently reinforcing this preference among scientists.
Interestingly, personal experience plays a significant role in shaping scientists' preferences. Those who work with a particular animal group tend to view it more favorably after their initial encounter. This suggests that increased exposure to "ugly" or "scary" animals could help shift perceptions and encourage more balanced research.
The consequences of this bias are concerning, particularly as human activities accelerate biodiversity loss. Many insect species remain poorly understood, and we may lose valuable benefits they provide to ecosystems before we even discover them. Research on seemingly unappealing animals, such as spiders and snakes, has led to important medical advancements, highlighting the potential benefits of studying less charismatic creatures.
To address this issue, we need to change our perception of animals and recognize their importance in ecosystems. Efforts from organizations like Invertebrates Australia and social media influencers are already helping to showcase the fascinating roles played by invertebrates. However, more support from governments and universities is needed to fund research on underrepresented species and groups.
By doing so, we can ensure that scientific progress and the preservation of biodiversity benefit from a more comprehensive understanding of the natural world.
