Nevertheless, the educational and qualification level of people in the industrialized countries has risen strongly.

There is neither evidence nor proof for this theory.</q></cite><span title="ctx_ver=Z39.88-2004&rft_val_fmt=info%3Aofi%2Ffmt%3Akev%3Amtx%3Abook&rft.genre=bookitem&rft.atitle=Do+the+Dumb+Get+Dumber+and+the+Smart+Get+Smarter%3F&rft.btitle=Heritability+of+Intelligence&rft.pages=37-39&rft.pub=Springer&rft.date=2022&rft_id=https%3A%2F%2Fapi.semanticscholar.org%2FCorpusID%3A244640696%23id-name%3DS2CID&rft_id=info%3Adoi%2F10.1007%2F978-3-658-35321-6_9&rft.isbn=978-3-658-35321-6&rft.aulast=Fischbach&rft.aufirst=Karl-Friedrich&rft.au=Niggeschmidt%2C+Martin&rft_id=https%3A%2F%2Flink.springer.com%2Fchapter%2F10.1007%2F978-3-658-35321-6_9&rfr_id=info%3Asid%2Fen.wikipedia.org%3ADysgenics" class="Z3988"></span> Citations in original omitted.</span> </li> <li id="cite_note-Dysgenics_1996-6"><span class="mw-cite-backlink"><b><a href="#cite_ref-Dysgenics_1996_6-0">^</a></b></span> <span class="reference-text"><link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1238218222"><cite id="CITEREFLynn1997" class="citation book cs1"><a href="/wiki/Richard_Lynn" title="Richard Lynn">Lynn, Richard</a> (1997). <a rel="nofollow" class="external text" href="https://dn790007.ca.archive.org/0/items/Dysgenics-Richard-Lynn/Dysgenics-Richard-Lynn.pdf"><i>Dysgenics: Genetic Deterioration in Modern Populations</i></a> <span class="cs1-format">(PDF)</span>. <a href="/wiki/Greenwood_Publishing_Group" title="Greenwood Publishing Group">Praeger Publishers</a>. <a href="/wiki/ISBN_(identifier)" class="mw-redirect" title="ISBN (identifier)">ISBN</a> <a href="/wiki/Special:BookSources/9780275949174" title="Special:BookSources/9780275949174"><bdi>9780275949174</bdi></a>.</cite><span title="ctx_ver=Z39.88-2004&rft_val_fmt=info%3Aofi%2Ffmt%3Akev%3Amtx%3Abook&rft.genre=book&rft.btitle=Dysgenics%3A+Genetic+Deterioration+in+Modern+Populations&rft.pub=Praeger+Publishers&rft.date=1997&rft.isbn=9780275949174&rft.aulast=Lynn&rft.aufirst=Richard&rft_id=https%3A%2F%2Fdn790007.ca.archive.org%2F0%2Fitems%2FDysgenics-Richard-Lynn%2FDysgenics-Richard-Lynn.pdf&rfr_id=info%3Asid%2Fen.wikipedia.org%3ADysgenics" class="Z3988"></span></span> </li> <li id="cite_note-7"><span class="mw-cite-backlink"><b><a href="#cite_ref-7">^</a></b></span> <span class="reference-text"><link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1238218222"><cite id="CITEREFConleyLaidleyBelskyFletcher2016" class="citation journal cs1">Conley, Dalton; Laidley, Thomas; Belsky, Daniel W.; Fletcher, Jason M.; Boardman, Jason D.; Domingue, Benjamin W.
