[Fallout]What exactly is Vault-Tec's motivation to create vaults that exist solely to conduct psychological experiments?

The vaults were a safe gaurd for nuclear apocalypse (at least as far as the general public knew). Meaning that no one was going to be in them unless the bombs started falling.

So why did Vault-Tec use them as large scale mouse-in-maze experiments? There are no corporations (let alone any sense of wealth or economy) in the wasteland to profit on the research. There's little to no point in conducting psychological science when we're all just trying to make it to tomorrow in one piece. There isn't much good in behavioral science or psychology when most people have been forced back to hunter gatherer lifestyles. What were their motivations?

Vault-Tec was an Enclave controlled company.  One of the Enclave's plans was to leave the planet and colonize another if nuclear war was imminent.  This would require them to be in space for a long period of time.  Some of the experiments were done to see how humanity would handle such a journey physically or mentally.  However the Enclave scrapped the evacuation plan and decided to rebuild America after the bombs have dropped.
