All research is provisional

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.
