The “review display preferences” available in the review settings page of your private dashboard allow you to choose your default display preferences for any reviews you add to your Publons account. The standard default setting is to display only the journal you reviewed for and not to publish the review’s content.
Any new reviews added to your account will have this default preference set when it is created. If you wish to update the preferences of all of your reviews at once then you can select “Apply to all my existing reviews” before saving your preferences. Review display preferences can be updated on a per-review basis from the review edit page.
