I've recently obtained some results which I have not found in the literature explicitly. Namely they are hinted in certain published literature, but very shortly and not in a very constructive sense.

After consulting with several people with experience in academia, I was told that it is frowned upon to publish these results more explicitly. I therefore decided to not write these results out properly.

Following this experience I was wondering whether there is a requirement when working on new projects to verify whether certain results are 'folklore'? Should one consult with an expert in the field before trying to publish results? Is it frowned upon to write something out explicitly, while trying to extensively discuss the result, and upload it to the Arxiv?

I should mention that some of my obtained results seemed not known by people in the field in my working group. I also wished I could refer to some of these properties in related topics.
