Everyone who submits an entry to the Competition through the submission form will be regarded as a Competition Entrant; however only those whose essays are deemed eligible and posted to the site will be regarded as "Essay Authors." Each eligible essay will be read and rated (scored between 1 and 10) by at least two Expert Readers (chosen by FQxI). FQxI Members and other Essay Authors will also have the ability to score essays. Essay Author Finalists will be those achieving the highest scores and/or those recommended by the Expert Readers. Essays can also be "liked" and commented on by the public.

For further clarity, see below for definitions of types of Competition participant:

  • Competition Entrant: Anyone who enters the Competition by submitting an entry through the submission form.

  • Essay Author: All Competition Entrants who receive a confirmation of eligibility from FQxI. Essay Authors have essays posted in the Competition. All Essay Authors will be anonymous, with names and bios withheld until the winners are announced.

  • FQxI Members: Scientists and outreach specialists FQxI has invited to be Members. A current list of FQxI Members is available here.

  • Expert Reader: Two or more people, selected by FQxI, to read and rate eligible essays. This review will happen during the general voting period to ensure all essays are read. Expert Readers provide FQxI with more than one fair assessment of each essay in case of any rating fraud.
