The principles and practice of effective altruism are closely connected to the principles of Economics. EA's engage economic concepts, arguments, and theoretical and empirical "results" throughout their work. However, these principles are sometimes misunderstood or mis-stated, sometimes alluded to but not considered in depth. The terminology itself can sometimes be muddled between EA, rationalist, decision theory, computer science, and academic economics communities. This leads to confusion and barriers to engagement.
