Esta press&atilde;o tem criado situa&ccedil;&otilde;es onde o cientista procura aumentar as suas chances de publicar seu artigo.&nbsp;<\/span><\/div>\n<div style=\"text-align: justify;\"> \t&nbsp;<\/div>\n<div style=\"text-align: justify;\"> \t<span style=\"font-size:14px;\"><span style=\"font-family:arial,helvetica,sans-serif;\">Sabemos que as pesquisas que trazem novidades apresentam mais chances de serem aceitas. Isto termina por incentivar os cientistas a buscarem os resultados que possam agradar mais aos pareceristas e editores dos peri&oacute;dicos.&nbsp;<\/span><\/span><\/div>\n<div style=\"text-align: justify;\"> \t&nbsp;<\/div>\n<div style=\"text-align: justify;\"> \t<span style=\"font-size:14px;\"><span style=\"font-family:arial,helvetica,sans-serif;\">Usando 641 artigos publicados em tr&ecirc;s peri&oacute;dicos de excel&ecirc;ncia na &aacute;rea de economia (American Economic Review, The Journal of Political Economy e Quarterly Journal of Economics) quatro pesquisadores investigaram os resultados dos testes estat&iacute;sticos. Isto significou analisar mais de 50 mil testes estat&iacute;sticos, j&aacute; que cada artigo possui em m&eacute;dia 78 testes e mais de tr&ecirc;s mil tabelas. Como os artigos foram publicados entre 2005 e 2011, a investiga&ccedil;&atilde;o corresponde ao estado da arte da pesquisa na &aacute;rea de economia.<\/span><\/span><\/div>\n<div style=\"text-align: justify;\"> \t&nbsp;<\/div>\n<div style=\"text-align: justify;\"> \t<span style=\"font-size:14px;\"><span style=\"font-family:arial,helvetica,sans-serif;\">O resultado n&atilde;o foi uma grande surpresa: uma vez que os peri&oacute;dicos gostam das pesquisas que rejeitam a hip&oacute;tese nula, os resultados apresentam uma grande distor&ccedil;&atilde;o. Os valores do &ldquo;valor do p&rdquo; que os pesquisadores encontraram parecem um desenho de um camelo, com muitos valores acima de 25%, um vale entre 10% e 25%. Isto parece indicar que os pesquisadores &ldquo;inflam&rdquo; os resultados, tornando-os mais pr&oacute;ximo daquilo que se esperam os peri&oacute;dicos.&nbsp;<\/span><\/span><\/div>\n<div style=\"text-align: justify;\"> \t&nbsp;<\/div>\n<div style=\"text-align: justify;\"> \t<span style=\"font-size:14px;\"><span style=\"font-family:arial,helvetica,sans-serif;\">Leia Mais em BRODEUR, Abel et al.
