It takes one cause as a condition for something else to occur and then states that the latter won't occur when the condition is observed to be untrue.Affirming the Consequent - correct answers is a logical fallacy that involves taking a true statement and assuming the converse form would be true as well. Formally, we can represent this fallacy as follows: If X is the case, then Y is also the case. Y is true, so X must be true as well. anchoring and adjustment - correct answers the tendency to judge the frequency or likelihood of an event by using a starting point (called an anchor) and then making adjustments up or down (a cognitive heuristic where a person starts off with an initial idea and adjusts their beliefs based on this starting point.) availability - correct answers estimating the likelihood of events based on their availability in memory; if instances come readily to mind (perhaps because of their vividness), we presume such events are common EX: two girls saw a plane crash on the news and cancel their flight presuming they will meet the same fate.
