[WH40K] How do the Tau have emotions and personalities if they lack a strong connection to the Warp?
gpt
You sort of have it backwards.

It isn't that your emotions and personality are a consequence of the Warp, rather, the Warp is a direct consequence of those emotions. Just because someone has emotions does not necessarily require a strong Warp presence. Blanks/Pariahs have literally no Warp presence and they are still capable of having emotions. 

Our emotions feed INTO the Warp. That is how the entities we know of as Chaos Gods came to be in the first place. They didn't already exist, exerting force on the sentients of the galaxy. Instead, they came to be as a direct result of the emotions of those sentients.
