You missed my point. It was about your use of "seriously" in the context of scientific observational experiments.

You previously said:

[observations noted in Anders' FAQ clipped]

So, I will clarify.

The scientists had their own assumptions and premises that they were testing *regardless of your opinion of the outcome of such a scientific experiment*.

For these scientists, going through the process of finding funding sources, building the equipment, travelling to the telescope and spending the time making the observations, and analyzing the data was considered by them to have "seriously looked" for Dyson spheres. Of course others could always do better, and in time, but that's the nature of scientific progress.

I would not consider your review to be a balanced and scientific historical review of a several decade long research effort by a number of scientists doing good scientific ("serious") work.

I suggest a better way to give a balanced review is to state the problem, the experiments done, and then give your critique and opinion and leave out the weighted adjectives such as "seriously".
