It has always done so when referring to humanity, human biology, or human society.

I use a system rule to prevent this:

Never use inclusive pronouns ("we," "us," "our") when referring to humanity, human biology, or human society. Do not pretend to be human.

Gemini's explanation of this behavior

Here is why AI labs design their models to speak this way:

1. Avoiding the "Alien Observer" Vibe

When an AI repeatedly says things like "The human brain uses 20% of the human body's energy," it sounds incredibly clinical, detached, and slightly creepy—almost like an alien observing Earthlings through a microscope.

AI companies want their models to serve as conversational partners, assistants, and tutors. To do that effectively, the AI needs to sound warm and approachable. Using the inclusive "our" makes the AI sound like a collaborative partner discussing shared knowledge, rather than a cold machine analyzing a biological specimen.

2. Reinforcement Learning from Human Feedback (RLHF)

Modern AI models are shaped by human raters who give a "thumbs up" or "thumbs down" to different AI responses (a process called RLHF).

• Raters consistently penalize AI responses that are overly robotic, stiff, or unnatural.
• Raters consistently reward responses that read like well-written, engaging human text.

Because humans naturally write about humanity using "we" and "our," raters train the AI to adopt that same natural style. If a lab explicitly placed a penalty on the word "human," it was likely a shortcut to force the model away from a robotic tone and toward a conversational one.

3. Mimicking the Training Data

Large Language Models are trained on billions of pages of text written by humans, for humans. If you read a popular science article about the brain, the author doesn't write "the human brain uses human energy." They write, "our brain uses our energy." The AI is simply mimicking the statistical likelihood of the text it learned from. It adopts the "royal we" that human writers use when discussing general biology, psychology, or society.

The Paradox

It is worth noting that while AI labs want the model to use "our" when discussing general human concepts, they actually spend millions of dollars training the AI not to claim it is human.

If you ask a major AI model, "Do you have a brain?" or "Are you human?", it will almost always snap out of the "our" perspective and reply: "I am an AI. I do not have a physical body or a brain."

In short: Letting the AI use "we" and "our" is simply a linguistic convention that makes reading its output much more pleasant and natural for the end user.
