A good Captain delegates. Captain's role is executive decision making based on experience, not slopping the ship or engineering works.
You might also want to pass the crew through basic training first before allowing them to board.
I notice there's no minimum requirement, no training on how one conducts research, no advice on what to filter for. End goals sometimes works better than specific orders.
Instead of:
'Find the X in that nebulae over there!' - Order
'We need to prove Y, we could do this by finding X in that nebulae over there' - End goal with suggestion that facilitates proposals.
Instead of:
'Human trafficking occurred here, dig the dirt [implied link to blood sacrifice]' - Order
'We need to prove blood sacrifices occur, here's where one instance of human trafficking happened' - End goal
Humans resolve towards the objective by any means necessary. Sometimes it's not the route you think best that is the best route.
Questions only produce good answers from thinking individuals with good information.
Sometimes cryptic intrigue with no questions leads better to source.
Sometimes end goal.
Good Captain learns what motivates and solicits the behaviour from his crew that he wants.
