Yes, except I want them to establish cognitive biases. Let's leave off that 'risk' part, as the risk is already inherent when you bark up wrong trees throughout the investigation. (time loss is the result of the risk posed by uncertain guesswork)

Let's get rid of that 'instead' you used, too. Sneaky! There's no reason for 'establish cognitive bias' and 'find the truth' to be exclusive from one another, is there?

So here's the new cleaned up version I think I can get behind :

"I would like the FBI to establish cognitive biases as a tool towards the goal of finding the truth."

Much better!
