Should I still submit if my final results are not good?
There is a big problem called publication bias: only studies that &quot;find something&quot; get published. In part this bias is due to journals being less likely to accept papers with negative findings. In part this is due to researchers not even submitting the papers. So, the fact that you submitted those papers is an important and positive step you have taken to (try to) reduce publication bias. However, it is an uphill battle.
