Step 1: Receive The Information/ Claim
Step 2: Always Be Skeptical
Step 3: Research The Claim For Validity
Step 4: Formulate Opinion Based On Sound Science
Step 1: So let's say that someone has made a claim that GMO's actually do not increase yields and do not aid a starving world.
Step 2: Hmmmm, that doesn't make sense to me. What I currently know about GMO's is that they are designed to be grown or raised in an environment that they typically wouldn't so it makes sense that they would have better yields.
Step 3: NEVER just go to google and click on the first article you see! You need to obtain information from MULTIPLE and CREDIBLE sources! Google Scholar, and websites that end in .Edu or .Org are very reputable sources. But anyway, after doing less than 5 minutes of research I could find a ton of articles that tout the benefits of GMO's including yield, decreased pesticide usage, and even increased farmer profits. *You can read one such article here:
http://www.geneticliteracyproject.org/2014/11/19/gmo-crops-increase-yields-benefit-the-environment/, by the Genetic Literacy Project, where Science Trumps Ideology.
Step 4: After doing research on the topic, I come to the conclusion that maybe GMO's are not that bad, in fact they can be useful to farm around the world and to an ever increasing population.
