p. 278, Table 2: The “Percent of variance” reported for each factor is for the unrotated rather than rotated factor matrix.  Of course, the variances explained by the Varimax rotated factors are much more equally distributed, namely, 16.4, 15.4, and 14.8.

pp. 795-796: This investigation was conducted before the advent of modern methods of analyzing cross-sectional time-series data (e.g., hierarchical linear models). Consequently, the method chosen to control for historical time and individual differences had the inadvertent effect of negating the possibility of identifying linear functions of age. Even so, the curvilinear functions of age still hold, along with any effects of the other substantive independent variables.

An erratum was printed on page 1097 in the same volume of the journal, but the suggested statistical analyses have been superceded by more recent developments in the treatment of longitudinal data, rendering these corrections irrelevant.

pp. 248-249: This investigation was conducted before the advent of modern methods of analyzing cross-sectional time-series data (e.g., hierarchical linear models). Therefore, the introduction of two sets of controls – date and the individual-difference dummies – had an unforeseen effect, namely that the linear age term was overcontrolled. It is not possible under this design to detect any linear longitudinal changes. However, the curvilinear effects still hold.

p. 219, Table 9.1: Because this table merged results from several different publications that had different publication dates, some of the statements are inaccurate. The most striking example is the assertion that IQ 121 is “about the average for college graduates in the United States.” This statistic is no longer valid now that almost one third of the population goes to college, which must necessarily lower the average IQ for graduates.

p. 62, column 2: The scores used for “Age at Nobel Prize” were incorrect because the ages at time of doing prize-winning work were inadvertently inserted for the first three award categories. However, because the rank ordering of the four disciplines remains completely unchanged – first physics, then chemistry, followed by physiology or medicine, and lastly economics – the substantive conclusions still stand. Nobels for achievements in disciplines nearer the top of the hierarchy are bestowed at younger ages than are Nobels for achievements in disciplines nearer the bottom of the hierarchy. Although the correlation would be reduced in absolute magnitude, the correlation was not reported in the article anyway. The only change is that the slope of the appropriate line in Figure 1 is less steep than there depicted.

Unfortunately, I did not see the proofs before this article was published, so a number of errors crept into the final product.

p. 8, 2nd paragraph, sentence beginning “Combinations generated by step-by-step algorithmic methods have the value v = 1, whereas those generated by pure chance or yield v = 0″ must omit the “or” between “chance” and “yield” (albeit pure chance is not the only combinatorial procedure where v = 0).

p. 8, 3rd paragraph, 1st sentence should begin “It should be apparent that if (1 – p), u, or (1 – v) equal zero, then c must equal zero” (i.e., the first and third factors must be inverted by subtracting from unity).

p. 13, 2nd complete paragraph, the sentence beginning “Even if a creator happened to produce a highly useful combination, he or she would receive no credit if the combination’s utility was not already known in advance.” The missing “not” is critical here.

Finally, in retrospect, another constraint should have been imposed on p, namely, that p could not be smaller than uv, the product of the utility and the knowledge value (i.e., uv < p < 1). However, when the Monte Carlo simulations are rerun with that constraint in place, the outcomes are virtually unchanged.


423. Simonton, D. K. (2012i). Foresight, insight, oversight, and hindsight in scientific discovery: How sighted were Galileo’s telescopic sightings? Psychology of Aesthetics, Creativity, and the Arts, 6, 243-254.

p. 245, Footnote 4: It should be noted that this sightedness metric provides a necessary but not sufficient measure. A necessary and sufficient measure requires the addition of a third parameter that gauges the extent to which the utility is already known (see Simonton, 2012b, 2012q, 2013h). As a result, the given metric overestimates set sightedness. One fascinating implication of this three-parameter measure is that a creative idea can indeed emerge in a set where S = 0, contrary to the “paradox” mentioned in the article. At the same time, a set where S = 1 cannot possibly contain a creative idea.

p. 248, 2nd full paragraph, 3rd sentence: “Lodovico” should be “Ludovico” as in Footnote 6.

pp. 249, 252: On January 12, 2013, Owen Gingerich informed me that the movement of Neptune relative to the fixed stars would have been virtually impossible to notice under the circumstances. Hence, the oversight is mine rather than Galileo’s.

p. 103, Footnote 7: This should begin “I have not even mentioned a fifth potential implication” (rather than fourth).


437. Simonton, D. K. (2013a, January 31). After Einstein: Scientific genius is extinct. Nature, 493, 602.

This little comment was originally designed as a “thought piece” in which I merely raised the issue of whether scientific genius has become obsolete in the natural sciences. In the original draft, the speculative nature was obvious. Yet the journal editors wanted something stronger, more forthright, more controversial. After several revisions, the end result achieved their goal, but much of the writing is not my own. The title was changed along with the summary as well. Worse still, the editors added something to the title without asking my permission. This unauthorized addition led many readers to believe that I was claiming that Albert Einstein was the last genius. Curiously, even when the publisher sent me the “final” reprint for distribution (subject to a few days embargo), it did not contain that insertion, so the two words must have been added at the last minute without my consent.

Therefore, to set the record straight, the following opening in the printed copy

After Einstein: Scientific genius is extinct.
Dean Keith Simonton fears that surprising originality in the natural sciences is a thing of the past, as vast teams finesse knowledge rather than create disciplines.

should be replaced with what actually I wrote in the last revision before I saw the galley:

Is scientific genius obsolete?
Dean Keith Simonton proposes that the phenomenon of genius has become irrelevant in understanding outstanding creativity in the modern natural sciences.

I complained about the change in the galley, saying that I would not be willing to defend the revised statement – but to no avail. Although I was temporarily relieved to see that the press release used my version rather than the editor’s, the editor’s version is what actually appeared in print, again with the “After Einstein” gratuitously inserted as the main title! An author apparently has only so much control when it comes to Nature comments. The resulting hybrid has provoked more controversy than any other publication associated with my name. Obviously that was the editorial design. Would they have committed this editorial transgression against Einstein himself?

In any event, the first draft can be found here. Not surprisingly, it contains some minor errors. In particular, Einstein published four revolutionary papers rather than three and the Olympic slogan is most properly “faster, higher, stronger.” But the main points are closer to what I originally had in mind.

p. 3: “The two sets of paired bases had to have the same length and parallel configuration in order to fit on the inside of the DNA molecule (with its two outside sugar spines)” should be shortened to “The two sets of paired bases had to have the same length and parallel configuration in order to fit within the DNA molecule”

This erratum concerns an apparent error of omission rather than of commission: This brief one-page comment fails to cite Simonton (2014l) on which it was based. Indeed, the comment is nothing more than a short summary of the article in Perspectives of Psychological Science. The omission arose because at the time that 2014b was going to press, the subtitle had not yet been settled for in 2014l. Indeed, the disagreement was so pronounced that the copyright forms could not yet be signed. So at the last minute it was deemed better just to omit the citation altogether rather than have a permanently incorrect reference containing an utterly unacceptable subtitle. Fortunately, no other authors were involved besides me, so I am the only one missing the self-citation!

Another occasion where editors decided to change my title without asking my permission before publication (see also here). The original title was:

The reason why the editors decided to change the title without the author’s permission should be obvious even if unacceptable.

495. Simonton, D. K. (2015m). “So we meet again!” – Replies to Gabora and Weisberg. Psychology of Aesthetics, Creativity, and the Arts, 9, 25-34.

When this reply went through proofs, I had a major disagreement with the APA technical editors regarding whether the 2014 date of the target article in the online first version should be retained after the actual publication date had been moved to make it the lead article of 2015 (see Simonton, 2015n). They insisted that the online first date is retained no matter what! Hence, every citation to “Simonton (2014d)” actually refers to an article published in 2015. Even more absurdly, in the References this publication was nonetheless placed in Volume 9, pages 2-14, which is absolutely impossible because it was Volume 8 that came out in 2014. It gets worse, for even if the editors repeated the same error for the Gabora comment, a totally different error is inserted for Weisberg’s comment, namely a citation not to the target article but rather to my 2015 reply, which makes no sense whatsoever given that he did not respond to the reply but rather to the original article. The algorithms that work for Google Scholar, the Web of Science, and other indexing services will have a great time figuring what is what! Perhaps the human error will be compounded with computer error.
