There are two different situations for which a different (scientific) method is appropriate.
Within these two situations many different methods may eixist.
So even at the top level of classification there is no one single 'scientific method'.
More specifically;
In the situation were we are discussing applied science, particularly engineering, we have the idea of the independent check.
When designing or assessing a bridge, an aircraft, a dam or whatever current practice demands that the desing is checked by an independent method and person(s).
So a bridge deck may be designed by one person or team using finite element methods, and checked by another team using energy methods, plastic hinge theory or Klein-Logel charts.
At a lower level operations should be carried out in a 'self checking' manner which incorporates and independent check.
A good example of this is the surveying practice known as the rise and fall method which submits surveying calculations to verification by an alternative arithmetical process.
Measure twice, cut once.
That was the first situation, the known.
The second one is where fundamental research is undertaken.
Here an independent check is sometimes possible ( as in the geological dating examples in another's post) , but often only one system of measurements are possible or available.
Sometimes the actual measurement is a chance observation.
In this case efforts may (should) be made not only to repeat the expereiment but also to take further observations in a range of conditions to place the
initial measurement in context and give confidence and credence to it.
There is another thread just posted in scientific news here, concerning carbon fixing into the rocks, where this process is just beginning.
The whole point of this is that mere repetition is (as you rightly said) dangerous.
Verification should be by different (=independent) means.
And if there are independent means if follows that there is more than one way.
Enjoyed reading your post Studiot... Thank You

Dawkins books are good... As stated they are more in line for the general reading purposes and the general pubic.

"Surprisingly, about the same amount of Neanderthal ancestry is seen in all non-African genomes, even people from places where Neanderthals never lived, like the New World."
Thats what I was thinking...... Thanks for sharing..
