I think Hawk’s hit what I feel is an issue here.
When you’re developing models, simulations, predictions, or anything else, the Verification stage is done early on to make sure that your artifact matches the data you currently have. After you’ve built it, you Validate to make sure that what do did hit your goal.
Taken from that perspective, the use of “validation” in this context risks two things: watering down the importance of verification/validation, and pushing UX further towards the reactive, design-approval role that its constantly fighting to move away from. Validation is important to close the loop and provide the iteration that any human-centered design thrives on.
