Document Summary
Theories in political science never proven in certain & fast way. Deductive reasoning uses previous theory, principles, evidence, etc first. Qualitative more writing, detailed, open to some interpretation. Non empirical evidence has not happened, can"t eventually be proven until it happens. We can only study what has already happened!! Best way is using both quantitative & qualitative empirical evidence. Quantitative is usually easier & faster to get. Empirical critiques mean theory didn"t hold up with data. Theoretical critiques mean theory not supported by logic. Scope conditions mean theory only holds for certain types of cases. Positive & negative relationships if more of one leads to more of another or more of one leads to less of another. Validity--does indicator measure what we want to measure. Measurement error (episodic vs. systemic)--does the measurement record real world accurately. Bias--measurement more likely to obtain one outcome than another.
