Synthese publishes articles in all the fields covered by the subtitle. These include: the theory of knowledge; the general methodological problems of science, such as the problems of scientific discovery and scientific inference, of induction and probability, of causation and the role of mathematics, statistics and logic in science; the methodological and foundational problems of different sciences. Insofar as they have philosophical interest: those aspects of symbolic logic and of the foundations of mathematics which are relevant to the philosophy and methodology of science; and those facets of the ethics, history and sociology of science which are important for contemporary topical pursuits.

Impact Factor

Impact factor (IF) is a scientometric factor based on the yearly average number of citations on articles published by a particular journal in the last two years. A journal impact factor is frequently used as a proxy for the relative importance of a journal within its field. Find out more: What is a good impact factor?

III. Other Science Influence Indicators

Any impact factor or scientometric indicator alone will not give you the full picture of a science journal. There are also other factors such as H-Index, Self-Citation Ratio, SJR, SNIP, etc. Researchers may also consider the practical aspect of a journal such as publication fees, acceptance rate, review speed.

The h-index is an author-level metric that attempts to measure both the productivity and citation impact of the publications of a scientist or scholar. The index is based on the set of the scientist's most cited papers and the number of citations that they have received in other publications
