It could and should also count as “Ethos of the Blogger”

says Tyler Cowen:

•All research raises as many questions as it answers
•All research is difficult to interpret and to draw clear conclusions from
•Qualitative research may be vital to elaborate experience, suggest narratives for understanding phenomena and generate hypotheses but it can’t be taken to prove anything
•Quantitative research may be able to show hard findings but can rarely (never?) give clear answers to complex questions

And yet, despite all the challenges, it is still worth attempting to encourage an evidence-based approach, since the alternative is to continue to develop practice based only on assumption and belief.

Inspired by Rodney King, I can only add, "Can't we all just get over ourselves?"
