Table 7 Criteria to brainstorm about arenas (See Clarke, 2003 p. 124)

• Around the chosen arena, no major social worlds have appeared

Our literature review shows multiple perspectives over the DIY science phenomenon, as well as its multi-faceted intrinsic nature. DIY science contains different actors and collectives that respond to different cultures and practices. No actors at both research phases stressed the prevalence of any SW against others.

• Historically, we have a sense of the changes that have interested the arena at stake

Many aspects have characterized the latest developments of various instances of DIY science (e.g. new technologies such as 3d printing), which can therefore be considered a further development of an already existing phenomenon

• Social worlds can in turn be deconstructed in arenas

We think this could be the case of DIY biology or other SWs within DIY science (e.g. IT hacking, the Maker Movement, etc.). We explore this possibility by offering two distinct possibilities of mapping.
