Jesus, the head guy couldn't come up with a single study they conducted that didn't support whoever was paying for it.
That's typical, though, even for completely ethical scientists, at least for a study that gets completed and published. Let me explain.
1) The payer asks you, the expert, to do a little literature work & study what is at the crux of the dispute, so that you can give them an informed scientific opinion (with no real lab work, jut your thoughts) on the matter.
2) Based upon your initial thoughts, they decide to pay you to do a full study or not. If they decide "not" because you tell them that they might not be right, then you are thanked and paid for your time. Your thoughts never get shared with anyone else. I've done this- told them that they may be wrong, and our work together was done. They decide either go to someone else as an expert or decide that "gee, maybe we should try to settle".
3) If they decide "do the study" then you start. They ask you to contact them at the very first hint of anything that may not fit their theory. If this happens, they tell you to stop right now. Then you are thanked and are paid for your time. Your preliminary results never get shared with anyone. I've done this too- told them that my preliminary data makes it look like they may be wrong, and so our work together was done. They either go to someone else as an expert or decide that "gee, maybe we should try to settle".
4) If everything looks to be supporting their theory, you complete all of the work and write it up in a neat little package that you then have to defend in deposition and in court. These are the studies that get published & shared.
They only make it to the end if they generally agree with what the payer wanted or at least contradict some of the claims of the other side. Otherwise, all parties would have bailed out much, much sooner.
I can only guess that Exponent was not willing to settle for the low pay they would have gotten if they stopped work as soon as they realized that if Walt Anderson's memory as to using the logo gauge is right, then they had NOTHING. They instead tried and tried to wiggle in the wind until they could hand-wave their way through a halfassed argument and get paid in full.
Or maybe Exponent wasn't even the first lab to look at it, but Wells thanked the others and paid them for their time, then those thoughts/preliminary results (not fitting with his agenda?) were never shared with anyone else. Remember when they were supposed to be working with Columbia? What happened there?
