Animals Are Sentient Too: How Human Bias Warps Our View of Intelligence

Humans have spent centuries congratulating themselves for being at the top of the pyramid of intelligence. We build cities, send rockets into space, and create abstract works of art. We use these achievements to claim dominance over the rest of the natural world. However, this view overlooks growing scientific evidence that animals are also sentient beings with their forms of intelligence. The belief in exclusive human supremacy rests not on fact, but on confirmation bias and selective definitions that favor our strengths.
 
Animals Feel, Think, and Choose
 
Neuroscience and animal behavior research demonstrate that many animals exhibit complex emotions and make conscious decisions. Mammals, birds, cephalopods, and even insects display behaviors that reflect memory, emotion, and social understanding.
​
Elephants return to the bones of their dead. Crows make and use tools to solve puzzles. Dolphins recognize themselves in mirrors and address one another with distinctive whistles that resemble their names. Dogs comfort humans in distress. Pigs’ complete memory and learning tests that rival those of chimpanzees. These examples demonstrate that animal consciousness extends across species and phyla, not just those most closely related to us.
 
The Cambridge Declaration on Consciousness, signed by leading neuroscientists, stated that animals possess the exact neural mechanisms required for consciousness. Octopuses, for instance, have distributed brains and use their limbs independently. Their behavior shows curiosity, problem-solving, and even mischief. These are not random instincts. These are signs of sentience.
 
Intelligence Looks Different Outside the Mirror
 
Humans measure intelligence by how well something resembles us. That bias shapes our definitions and excludes the cognitive strengths of other species. We favor language, tool use, and abstract math, then label other species as inferior because they don't score well on human-designed tests.
 
But intelligence develops through evolution and ecology. A migratory bird doesn’t need to read, but it navigates thousands of miles with no map. A squirrel remembers the locations of hundreds of hidden nuts across a forest. A spider builds webs using geometric precision and knowledge embedded in its body, not in equations.

Cognition does not follow a ladder with humans at the top. It spreads out across the tree of life. Each species evolves mental abilities that help it survive. Judging their intelligence by how closely they imitate us tells us more about our vanity than about their minds.
 
Human Bias Distorts the Picture
 
Humans define the rules and then claim victory. That is the core of our confirmation bias. We create tests that require spoken commands, hand dexterity, or written symbols. We ignore how a bat processes sound in three dimensions or how a fish communicates with electrical fields.
 
We did the same with marginalized human groups in the past. White colonizers used flawed “intelligence tests” to claim superiority over others. Male scientists declared women less rational. We now reject those views, but we still treat animals with that same prejudice.
 
The problem lies not in the animals, but in our inability to value intelligence that does not look like our own.
 
Sentience Brings Moral Obligations
 
Once we acknowledge that animals experience pain, joy, fear, and love, we confront an ethical crossroads. Our food system relies on treating sentient creatures as mere machines for meat production. Industrial farms confine pigs in crates that are too small for them to turn around. Chickens live in darkness and filth. Calves scream for mothers who never return.
 
These conditions reflect convenience, not necessity. If animals suffer, and we can avoid causing that suffering, then moral logic demands a change. We don’t need to grant animals the same rights as humans. But we must recognize their capacity to suffer and act accordingly.
 
Progress begins with empathy. As we once expanded moral concern to people of other races, genders, and nations, we now must consider species beyond our own.
 
Self-Destruction Characterizes Humans
 
A bigger issue is the demonstrable record of self-destruction, including genocide, slavery, wars, and intentional and thoughtless pollution that characterizes the rise of humanity.  Behaviors such as these are unknown among animal species. 
 
Redefining What It Means to Be Human
 
Recognizing animal sentience does not diminish the importance of humans. It makes us more honest. It invites humility. We did not evolve in isolation. We evolved in a web of other minds, other feelings, other forms of life with their own stories and perceptions.
 
Human intelligence deserves respect. But so does the wisdom of the elephant herd, the language of the whale pod, the memory of the crow, and the emotion in a dog’s eyes. We share this planet with minds we still barely understand.
 
Our future moral progress depends not on congratulating ourselves, but on widening our circle of empathy. It is time to see animals not as tools, toys, or tests, but as fellow sentient beings living conscious lives beside us.
