As a researcher, there are always certain apprehensions when submitting one's work in any peer-review journal. I would like to have inputs from my colleagues on this issue and how such apprehensions/ bais can be reduced.
I have good as well as very bad experiences with national and international journals. The biased attitude depends either on Editor/Subject Editor and the affiliation of the authors. However, there are many exceptions as well.
It is difficult for most peer review journals to be unbiased for the simple reason that most reviewers are unwittingly trapped in the vain path of promoting theirs and their colleagues areas of research to the detriment of promoting novel but good work and rejecting whatever they consider as nonconforming views.

Sometimes these journals are constrained in meeting review timelines and are also forced to use just anyone available.
Biasedness can be introduced by many other reasons but as a publisher you must learn to submit to blind peer review by cultivating a writing culture that is evidence based. Where your paper is based on original research, and you make efforts to communicate effectively you will have no reason to be scared of a blind peer review process. It is the duty of the Editors to work to eliminate bias and you must be prepared to follow constructive criticism which where objective can help in making your work more robust.
It is contingent on the journal's review policy. Where the selected reviewers are drawn for a similar set and know each other it could impair the review process.

Most of the established journals that are flagships in the respective subject areas are equally guilty. One would expect that they follow through guiding and facilitating
