Traditional Scientific Method as a Search Strategy

 

1. Steps in traditional science

learn about a system

make a hypothesis (that is testable)

perform controlled experiments or observations that will be able to disprove the hypothesis

modify the hypothesis based on results

repeat - getting either finer detail or more general

 

2. The scientific method works in a community

learn about the system from the literature

devote effort to improving the community's understanding of the system

the trust allows different members of this community to simultaneously explore different avenues

 

3. Hypothesis statement and testing is key to effective science

Strong Inference (2)

Multiple hypotheses - testing between hypotheses

1) Devising alternative hypotheses; not just a simple, throw away null hypothesis

2) Devising a crucial experiement (or several of them), with alternative possible outcomes, each of which will, as nearly as possible, exclude one or more of the hypotheses;

3) Carrying out the experiment so as to get a clean result;

1') Recycling the procedure, making subhypotheses or sequential hypotheses to refine the possibilities that remain, and so on.
