We understand an argument by starting at the top and reading down. We evaluate a map by start at the bottom of the map and work up:
Evaluation step-by-step:
1. The basis box: Is this a reliable source of information? Would you rate it as solid, shaky, or providing nil support?
2. The reason: What confidence do you have in this reason, given your assessment of its basis? Is it relevant to the position above? Would you rate it as providing strong, weak or nil support?
3. The position: What confidence do you have in the position, given the degree of support the reason provides? Would you accept it, reject it, or take no stand on it ('hmmm...')?
