.A scientist who wishes to devise a meaningful theory must take into account the concept of falsification. That is, he must phrase his ideas in such a way that at least one possible outcome of experimentation would, if observed, disprove the theory. An example of failure to meet this criterion would be the scientist ----

Which of the following best completes the passage above?

a.Whose theory is consistent with all currently known facts about its subject.
b.Who fails to engage in experimentation to explore the correspondence between his theory and reality
c.Whose theory fails to predict the actual observed outcome of experimentation.
d.Whose theory identifies correlations, but no actual cause and effect mechanisms.
e.Whose theory predicts all conceivable results of testing.

I was deciding between C & E. Also, I am trying really hard to keep it under two minutes. I didnt pick E, because it really doesnt say anything of importance. Just because he/she takes into consideration all possible outcomes, DOES NOT mean that he didnt account for a possibility of falsification. So, no not E, hmmm

IMO, E negates the concept of falsification. If all outcomes are predicted, then it is not possible that at least 1 outcome is not, as defined by the concept of falsification

Here is what I think guys. If I were to phrase the continuation of the sentence, it would have be something along the lines of: The scientist left no room to find any cracks in his theory (in laments terms). In other words, no matter how many observations, we WILL not find one observation that is contrary to his theory, or proves it wrong.

According to A: his theory is consistent with all known facts. Which could mean that one of those facts is contradictory to his theory, therefore can prove his theory wrong. Thus he didnt fail to meet the criterion. What so you guys think?

Wheeew, as always, I hate it when this happens. E was so tempted to go with E in the first place, change my mind many times and happens to be wrong. "It will payoff really well on the real thing."
