Endogeny Policy

The International Journal of Personality Psychology (IJPP) is committed to minimizing
endogeny and ensuring that all published articles are evaluated through an independent,
impartial, and transparent editorial process.

For the purpose of this policy, endogeny refers to the publication of research articles in which
at least one author is the Editor-in-Chief, an Associate Editor, an Editorial Board member, or
a reviewer of the journal. IJPP monitors the proportion of such articles and ensures that it
does not exceed 25% of published research articles in the latest calendar year.

1. Diversity of authorship and editorial participation
The journal aims to maintain diversity among authors, reviewers, and editors with respect to
institutions, countries, and research communities. IJPP is not intended to function primarily
as an outlet for the work of its editors or of any single institution or network.

2. Handling submissions from editors and board members
Editors and editorial board members may submit manuscripts to the journal, but are excluded
from all decision-making related to their own submissions. Such manuscripts are assigned to
an independent editor without a conflict of interest and are evaluated under the same
standards as all other submissions.

3. Conflict-of-interest management
Editors do not select reviewers or make decisions on manuscripts when there is a direct
conflict of interest, including recent co-authorship, institutional dependency, supervisory
relationships, or comparable personal or professional connections. Reviewers are likewise
expected to decline invitations when such conflicts exist.

4. Equal peer-review standards
All manuscripts are subject to the journal’s standard peer review process, regardless of the
authors’ institutional affiliation, editorial role, or professional network. Editorial decisions are
based solely on scholarly quality, originality, relevance, and compliance with ethical
standards.

5. Monitoring and corrective action
The Editor-in-Chief monitors authorship and editorial participation patterns in order to
identify and address any risk of excessive endogeny. If the proportion of articles authored by
editors, editorial board members, or reviewers approaches the 25% threshold, the Editor-in-
Chief may defer consideration or publication of further such manuscripts in order to preserve
editorial independence and compliance with good publishing practice.
Applicability of the endogeny threshold. DOAJ specifies that the 25% endogeny limit applies
to journals publishing a minimum of five articles per year. Given IJPP’s current publication
volume, it is unclear how this threshold applies in practice. It may be worth seeking
clarification from DOAJ on this point.
