Hi
Somewhat more positive evaluation of replication in psychology.

Given that the first author is "Mr Happiness" Daniel Gilbert
(for his background, see the Wikipedia entry on him:
https://en.wikipedia.org/wiki/Daniel_Gilbert_%28psychologist%29
and a shill for the Prudential financial services Co (see:
http://www.ispot.tv/ad/7IhP/prudential-age-stickers ), it is not
surprising that his co-authored paper has a more "optimistic"
view of reproducibility than the original research being critiqued
(for this article see:
http://science.sciencemag.org/content/349/6251/aac4716 ).
It is not surprising the Gilbert et al have a positivity bias but the
real question is whether it is warranted. Which is why if one
reads the Gilbert et al "happy news" article, they also read the
response to it by the members of the Open Science Collaboration
Replicability Project (OSC); see:
http://science.sciencemag.org/content/351/6277/1037.3.full-text.pdf+html
The abstract of the response follows:
|Gilbert et al. conclude that evidence from the Open Science
|Collaboration's Reproducibility Project: Psychology indicates
|high reproducibility, given the study methodology. Their very
|optimistic assessment is limited by statistical misconceptions
|and by causal inferences from selectively interpreted, correlational
|data. Using the Reproducibility Project: Psychology data, both
|optimistic and pessimistic conclusions about reproducibility are
|possible, and neither are yet warranted.
All three papers should be read as well as some related papers
and because some of the data is available, some additional
analyses might be attempted. If this is too much to ask, I'm
sure Gilbert would say "Don't worry, be happy".
