I guess you also know the budget was increased this year, so higher acceptance rates are expected. I saw in another forum that SSHRC even offered one-year postdocs to folks who were just below the cutoff last year.
I think this list includes the people who were offered fellowship in 2018. The competition that we applied will reveal the people who will be offered a fellowship in 2019. At least this is the most reasonable thing I can think ? I know it says 2018 competition in the website for this year, I think they are inconsistent on the website.
