Constructing sound arguments requires valid logic and reasoning. If your premises (reasoning) are incorrect they are considered to be “fallacies”. There are several different types of fallacies that exist. Once you recognize the fallacies you are more likely to avoid them in your reasoning. each fallacy with its definition in the chart below. ___ Also known as circular reasoning because the reasoning assumes the conclusion is true. ___ Sometimes occurs due to “peer pressure” or groupthink phenomenon when you may be influenced to conform to the opinion of the group. ___ A causal situation where we are unsure of the actual root cause of the issue.

In a deductive argument, the premises (reasoning) provide such strong support for the conclusion that, if the premises are true, then it would be impossible for the conclusion to be false.

rgument below with a conclusion. Your conclusion may be strong or weak depending upon the strength of your premises. Premise 1: Four-year-old Jeremiah likes to play with blocks.
