Is it Art?

Mondrian's work appears to be simple compositions

Lee (2001): art students could not identify genuine Mondrian compositions

But McManus (et al, 1993) found majority of subjects could distinguish between original and modified

Wolach (2005) found subjects preferred Mondrian's line spacings

=> general aesthetics?

BUT if they could chose own preference, then the preference for Mondrian spacings vanish

=> individual aesthetics?
