   Many Psychology Findings Not as Strong as Claimed, Study Says

   The past several years have been bruising ones for the credibility of the   
   social sciences. A star social psychologist was caught fabricating data,   
   leading to more than 50 retracted papers. A top journal published a study   
   supporting the existence of ESP    
   that was widely criticized. The journal Science pulled a political science   
   paper on the effect of gay canvassers on voters' behavior because of concerns   
   about faked data.   
      
   Now, a painstaking yearslong effort to reproduce 100 studies published in   
   three leading psychology journals has found that more than half of the   
   findings did not hold up when retested. The analysis was done by research   
   psychologists, many of whom    
   volunteered their time to double-check what they considered important work.   
   Their conclusions, reported Thursday in the journal Science, have confirmed   
   the worst fears of scientists who have long worried that the field needed a   
   strong correction.   
      
   The vetted studies were considered part of the core knowledge by which   
   scientists understand the dynamics of personality, relationships, learning and   
   memory. Therapists and educators rely on such findings to help guide   
   decisions, and the fact that so    
   many of the studies were called into question could sow doubt in the   
   scientific underpinnings of their work.   
      
   "I think we knew or suspected that the literature had problems, but to see it   
   so clearly, on such a large scale -- it's unprecedented," said Jelte Wicherts,   
   an associate professor in the department of methodology and statistics at   
   Tilburg University in    
   the Netherlands.
