Can one publish ideas well before one has evidence proving the ideas work? I am rather disappointed by the existing research in my area of interest. There is a big disconnect between the solutions practitioners need and what researchers look at.


I have read everything available on the subject in e-journals.
I have many ideas which I believe can solve some small problems in my field.
I also have ideas for paradigms (or major expansions of existing paradigms) which I believe can help the researchers and practitioners look at the problems in a different light.
I am not in a PhD program, so I lack the advice, time, resources, and know-how for setting up controlled experiments to validate these ideas, so I can only address them as thought experiments or identify the nearest related experiments not directly testing my ideas.


Can I publish short here-is-an-idea paper (e.g. “Proposed Solution for X” or “(new) Model for Y”) well before having any means of providing some proof?
Generally, no.

Insights are a dime a dozen. Insights with evidence are how science (social and natural) proceed.

Proceeding through your bullets:


You mention e-journals. Have you read the "literature" in traditional journals/books/whatever the field's standard is? There's a lot of good reason to be suspicious of e-journals, so you may not have a full view of the field.
Belief in ideas doesn't make them true(r). Sorry.
Is there a reason that you think that these expansions of paradigms haven't been considered? Are you sure that they really have never occurred before?
Perhaps that's the argument for obtaining a Ph.D. or research master's --- to demonstrate that ideas have empirical heft.


If you really want to make a difference, you will have to offer evidence that your ideas work or have worked, beyond the logic you offer.
