0 should override defaults
0 is the independent variable, and should appear in default_blank.

Result: a "0" value does not override any default. 

1 should override defaults
1 is the independent variable, and should appear in default_blank.



false should override defaults
Boolean false is the independent variable, and should appear in default_blank.
