In science, you must show your work, not just the conclusions (answers).
It helps provide insight into your assumptions, data, logic and decision making.
It does not matter whether your conclusions are right or wrong, if the assumptions, data, logic and decision making do not support your conclusions, the conclusion is dismissed.
Your conclusion might be right, yet you can still get less marks than the one whose work is more reproducible.
In science, the “what” only matters, if the “how” is reproducible.
Life as we know it, is becoming more and more a celebration of “what”, with any questions on “how” either taken as an affront to the achiever or as boring to the listener.
This is why success is so difficult to reproduce.
More and more people want to get full marks for the answers, without a need to show their work.
