Sure, I understand how research is done.
However, you could feasibly create components that allow for a certain
types of experiments and open up the analysis side to the community. I
think this could be a lot more successful than you'd expect - the community
has many smart people, and together we could decide and promote best
practice across projects/experiments. They'd also be able to drive
suggestions for what new components to implement to expand the experiment
space, and more generally grow interest in the work of the EE team.
I understand that what you're doing now is quick and dirty and just
trying to get something up and working, but I hope that longer term you
have in mind the capability of the community to help you in this kind of
endeavour. We're all keen to grow participation, and giving us tools to
experiment ourselves will ultimately be more effective than anything you
can do centrally.

Neither; the tools we have for running
experiments are largely
hand-build on an ad hoc basis. For data collection we have tools like
eventlogging, although they require developer energy to integrate with
[potential area of experimentation]. But for actually analysing the results
it looks very different.
Let's use a couple of concrete examples: suppose we wanted to look at
whether there was a statistically significant variation in whether or not
people edited if we included a contributor tagline, versus didn't. We'd
need to take the same set of pages, ideally, and run a controlled study
around an A/B test.
So first we'd display one version of the site for 50% of the population
and another for the other 50% (realistically we'd probably use smaller sets
and give the vast majority of editors the default experience, but it's a
hypothetical, so let's run with it). That would require developer energy.
Then we'd set up some kind of logging to pipe back edit attempts and view
attempts by [control sample/not control sample]. Also developer energy,
although much less. *Then*, crucially, we'd have to actually do the
analysis, which is not something that can be robustly generalised.
In this example we'd be looking for significance, so we'd be looking at
using some kind of statistical hypothesis test. Those vary depending on
what probability distributions the underlying population follows. So we
need to work out what probability distribution is most appropriate, and
then apply the test most appropriate to that distribution. And that's not
something that can be automated through software. As a result, we get the
data and then work out how to test for significance.
The alternate hypothesis would be something observational; you make the
change and then compare the behaviour of people while the change is live to
their behaviour before and after. This cuts out most of the developer cost
but doesn't do anything for the research support or the ad-hoc code and
tools that need to come with it.
