Differences of opinion in political subjects is an unanswered phenomenon and does not seem to fade away as the world turns more gender equal. This study aims to deepen the understanding of what is known in the scholarly literature as a gender gap. The correlation between more gender equal views and peaceful attitudes in foreign policy’s, earlier found in four Middle Eastern society’s is tested on the population of Sweden. Public opinion surveys from the SOM-institute are analysed with frequency- and contingency tables. The results show a gender gap in Sweden and that the relationship between more peaceful attitudes in foreign policy’s and a more gender equal perspective is also observed in Sweden. That relationship provides no satisfying explanatory force to the gender gap. The phenomenon remains unsolved, but this study extended the understanding and provided a few suggestions on how further studies could embrace the question and fill the knowledge gap.
