Are they Y-E-S people or are they true? If you’re not sure test them with the “worst idea yet”. If they’re all gong ho to go then maybe you should leave them before your wallet disappears. Of course they could just love your charisma so make sure your enthusiasm isn’t over selling your “dumb idea”. Yet even if so they still seem enthusiastic about something that appears clueless they should have some smart questions in return. Testing with your worst idea might give you the results you need even if it’s not the one you truly want to hear.
