Correction: Unrealistic comparative optimism: An unsuccessful search for evidence of a genuinely motivational bias.

[This corrects the article DOI: 10.1371/journal.pone.0173136.].

A portion of the figure legend for Table 1 is incorrectly displayed in the text of the Results section in the second and third paragraph of the section headed “Comparing the effects of perceived frequency and event valence.” The text in question is “Four of Weinstein’s original items…according to participants’ subjective ratings.” Please see the complete, correct Table 1 and caption here. The publisher apologizes for the error.

*p < .05.

**p < .01.

***p < .001. Four of Weinstein's original items were not included in this study. These were: "Dropping out of college" (to reduce any extra variance introduced as a result of participants being both first and second year students). "Decayed tooth extracted" and "Having gum problems" (as such events may not be future events for some of the sample), and "attempting suicide" (for ethical reasons). Events are classified here as positive or negative according to participants' subjective ratings.
