...and almost all of what animals do is controlled by instinct. Those instincts are coded in our genes. There is absolutely no thinking involved.

Yes, humans do things "without thinking" (instinctually) and then later they often rationalize it with arguments about why they did whatever they did. And usually those explanations are untrue--they are simply contrived on the spot to cover any doubt in their minds.

You're giving people--us--way too much credit for being aware of our own behavior, and the causes underlying our behavior.

We aren't.

Have you read the studies of people with certain forms of brain damage, which causes their one hand to not know what their other hand is doing? But if asked why they did whatever-it-was with their one hand--which their "rational mind" was oblivious to--their "rational" mind will immediately give a justification for it. No matter how stupid that justification may sound.

A partial explanation of what I'm talking about regarding brain damage:

After Damage to the Right Hemisphere - Right vs. Left Brain ...

Studies show that damage to the left and right hemispheres of the brain impacts hand movements differently. Left hemisphere damage can lead to difficulties with language, speech, and motor control of the right side of the body, including hand movements. Right hemisphere damage can cause issues with attention, spatial reasoning, and perception, also affecting movement on the left side of the body.

Here's a more detailed look:

Left Hemisphere Damage:

Motor Control:

Primarily responsible for the fine motor control of the right hand and arm. Damage here can lead to weakness, paralysis, or apraxia (difficulty with purposeful movements) on the right side.

Language:

The left hemisphere is dominant for language in most people, so damage can cause aphasia (difficulty with language production and comprehension).

Ideomotor Apraxia:

Left hemisphere damage can impair the ability to perform learned movements, especially those involving tool use, even when the person understands the instructions and can physically perform the movement.

Right Hemisphere Damage:

Spatial Processing:

The right hemisphere is crucial for spatial awareness, including perceiving the position of limbs in space, and for processing visual information from the left visual field.

Attention:

Damage to the right hemisphere can cause attention deficits, including unilateral neglect (failure to attend to the left side of space).

Gesture Production:

While the right hemisphere can produce gestures, damage here can lead to difficulties in the pragmatic aspects of gesture, such as using gestures to communicate or coordinate with others.

Important Considerations:

Contralateral Control:

Each hemisphere controls the opposite side of the body. So, damage to the left hemisphere primarily affects the right side, and vice versa.

Interhemispheric Communication:

The two hemispheres are constantly communicating and influencing each other. Damage to one hemisphere can disrupt this communication and affect the function of the other hemisphere as well.

Individual Variability:

The specific symptoms of brain damage can vary greatly depending on the location and extent of the lesion, as well as individual factors.

Bimanual Coordination:

While the left hemisphere is often considered dominant for motor control, both hemispheres are involved in bimanual (two-handed) movements. Damage to either hemisphere can affect bimanual coordination.

The above is from a chatbot--but I've read enough on the topic to spot obvious errors, and the text does not contain any obvious ones.
