5 Q In any event, in your expert report, and in your
6 testimony over the last two days, you used a looser
7 definition of "theory," correct?
8 A I think I used a broader definition, which is more
9 reflective of how the word is actually used in the
10 scientific community.
11 Q But the way you define scientific theory, you said
12 it s just based on your own experience; it s not a
13 dictionary definition, it s not one issued by a scientific
14 organization.
15 A It is based on my experience of how the word is
16 used in the scientific community.
17 Q And as you said, your definition is a lot broader
18 than the NAS definition?
19 A That s right, intentionally broader to encompass
20 the way that the word is used in the scientific community.
21 Q Sweeps in a lot more propositions.
22 A It recognizes that the word is used a lot more
23 broadly than the National Academy of Sciences defined it.
24 Q In fact, your definition of scientific theory is
25 synonymous with hypothesis, correct?

1 A Partly -- it can be synonymous with hypothesis, it
2 can also include the National Academy s definition. But in
3 fact, the scientific community uses the word "theory" in
4 many times as synonymous with the word "hypothesis," other
5 times it uses the word as a synonym for the definition
6 reached by the National Academy, and at other times it uses
7 it in other ways.
8 Q But the way you are using it is synonymous with the
9 definition of hypothesis?
10 A No, I would disagree. It can be used to cover
11 hypotheses, but it can also include ideas that are in fact
12 well substantiated and so on. So while it does include
13 ideas that are synonymous or in fact are hypotheses, it also
14 includes stronger senses of that term.
15 Q And using your definition, intelligent design is a
16 scientific theory, correct?
17 A Yes.
18 Q Under that same definition astrology is a
19 scientific theory under your definition, correct?
20 A Under my definition, a scientific theory is a
21 proposed explanation which focuses or points to physical,
22 observable data and logical inferences. There are many
23 things throughout the history of science which we now think
24 to be incorrect which nonetheless would fit that -- which
25 would fit that definition. Yes, astrology is in fact one,

2 many other -- many other theories as well.
