Lab notebooks are not personal things in cases of importance. Notebooks have 2 basic reasons for existing:
1. So that the researcher can follow his process to duplicate what he did the first time;
2. So that other researchers can follow the process so that they can duplicate the results of the first guy.
Anybody can glance at a writing and say that it was all fake. That's why we need the notebook... so that we can follow the process to get the results. If we can't determine the whole process, the whole operation, because the process is as unclear as your example below, there is no way to know if we are duplicating it properly. And there is no way to know if the process works or not as the report says.
In addition, the notebooks are signed or initialed by the researcher on every page, and the pages are all numbered in order in a bound book-style of notebook, to prove that it was written by the researcher. His name and address are included, so that we know where to contact him for details we don't understand.
You kinda have it backwards. We want proof, not some vague, generalized idea about something.
This "argument" doesn't make any sense at all... unless, perhaps, you simply don't understand what a published scientific paper is?
provides evidence of [...] It appears that
What kind of BS guesswork is being handed to us? And you are falling for it.
Since this report was accepted by the medical as proof without any proof, why should we accept anything that the medical says?
Okay, you may not understand what a scientific paper is, but you definitely don't understand the language of science. Please could you read Salty Spitoon's post above? That should cover it for you.
"It appears that" doesn't mean "Hey, I've had a random unsupported idea: x! Let's go with that!", instead it means something more like "based on the everything we've detailed here, the logical conclusion is x".
And I don't know how to respond to your objection to the phrase "provides evidence of"... that goes beyond the language of science, and suggests that you don't understand English.
