This is a theory about the consciousness of droids in the Star Wars universe and how most biological creatures of higher intelligence regularly dismiss, ignore, or wholly undermine the autonomy of droids. However, on multiple occasions we see droids ignoring orders, altering orders, and exercising independent judgement. The most concrete example comes from Episode IV: A New Hope when C-3PO and R2-D2 decide to split up in the desert rather than following hardwired programming. I also believe that they fall under the influence of the force and may have force sensitivity but lack the ability to actually manipulate the force. But, as Obi-Wan told Luke on the Millennium Falcon, the force moves through, surrounds, and touches every living thing.
