THE SCIENTIFIC METHOD毛羽
A‘Hypothes, ’ said Medawar in 1964, ‘are imaginative and inspirational in character’; they are ‘adventures of the mind’. He was arguing in favour of the position taken by Karl Popper in The Logic of Scientific Discovery (1972, 3rd edition) that the nature of scientific method is hypothetico-deductive and not, as is generally believed, inductive.

B It is esntial that you, as an intending rearcher, understand the difference between the two interpretations of the rearch process so that you do not become discouraged or
begin to suffer from a feeling of ‘cheating’ or not going about it the right way.nuts是什么意思
you belong to meC The myth of scientific method is that it is inductive: that the formulation of scientific theory starts with the basic, raw evidence of the ns - simple, unbiad, unprejudiced obrvation. Out of the nsory data - commonly referred to as ‘facts’-generalisations will form. The myth is that from a disorderly array of factual information an orderly, relevant theory will somehow emerge. However, the starting point of induction is an impossible one.
D There is no such thing as an unbiad obrvation. Every act of obrvation we make is a function of what we have en or otherwi experienced in the past. All scientific work of an experimental or exploratory nature starts with some expectation about the outcome. This expectation is a hypothesis. Hypothes provide the initiative and incentive for the inquiry and influence the method. It is in the light of an expectation that some obrvations are held to be relevant and some irrelevant, that one methodology is chon and others discarded, that some experiments are conducted and others are not. Where is your naive, pure and objective rearcher now?
E Hypothes ari by guesswork, or by inspiration, but having been formulated they can and must be tested rigorously, using the appropriate methodology. If the predictions you make as a result of deducing certain conquences from your hypothesis are not shown to be correct then you discard or modify your hypothesis. If the predictions turn out to be correct then your hypothesis has been supported and may be retained until such time as some further test shows it not to be correct. Once you have arrived at your hypothesis, which is a product of your imagination, you then proceed to a strictly logical and rigorous process, bad upon deductive argument - hence the term ‘hypothetico-deductive’.
F So don’t worry if you have some idea of what your results will tell you before you even begin to collect data; there are no scientists in existence who really wait until they have all the evidence in front of them before they try to work out what it might possibly mean. The clost we ever get to this situation is when something happens by accident; but even then the rearcher has to formulate a hypothesis to be tested before being sure that, for example, a mould might prove to be a successful antidote to bacterial infection.
G The myth of scientific method is not only that it is inductive (which we have en is incorrect) but also that the hypothetico-deductive method proceeds in a step-by-step, inevitable fashion. The hypot
hetico-deductive method describes the logical approach to much rearch work, but it does not describe the psychological behaviour that brings it about. This is much more holistic - involving guess, reworkings, corrections, blind alleys and above all inspiration, in the deductive as well as the hypothetic component -than is immediately apparent from reading the final thesis or published papers. The have been, quite properly, organid into a more rial, logical order so that the worth of the output may be evaluated independently of the behavioural process by which it was obtained. It is the difference, for example between the academic papers with which Crick and Watson demonstrated the structure of the DNA molecule and the fascinating book The Double Helix in which Watson (1968) described how they did it. From this point of view, ‘scientific method’ may more ufully be th ought of as a way of writing up rearch rather than as a way of carrying it out.
