Out of sight
The two men who go to the professor to ask about the utopian society just returned from serving in the Second World War. Form this detail, we can assume that the two were interested in the well-being of their country and that they were people who wanted to serve their country with all they got. The experience they had in war changed their perception of good and evil and when they returned home they no longer believed in the same things they used to believe in before going to war. Because of this, they became interested in finding a utopian society that will not ask them to risk their lives for their country. This element is ironic considering the fact that the two men used to fight in a war, trying to protect their country with all they got.
Not helping
The men who visit Walden Two notice that every woman in the community is very beautiful. Frazier assures them that no woman was selected due to her physical appearance and that the reason why the women all appear beautiful is because they are not compelled by fashion rules to wear certain items of clothing that do not suit them for the simple fact that fashion dictates what they have to wear. Ironically thus, while some may be inclined to believe that the fashion trends have the purpose of helping a person look better, it may not work for everyone and it may not benefit every person.
Equality
The impression left was that in Walden Two, the people were aiming for equality between the men and the women in the community. The visitors note however that the women are well-dressed while the men wear clothes that do not compliment them in the same way the clothes the women wore complimented their bodies. Frazier admits that while they try to achieve equality, there were still areas that they needed to work on. Ironically, the ones who had more advantages were not the men, but the women. This was something unheard of in the American society in the 1940s.
False sense of community
In the sixth chapter, the visitors are able to see that in Walden, no crowds ever form. The members of the community chose to gather in small groups instead of extremely large crowds like it often happens in big cities and rather than spending their time with people they do not know, they spend their time with those who are close to them. Frazier tells them that the reason why crowds were eliminated was because they created a sense of alienation. Instead of making people feeling less alone, big crowds have the opposite effect. His statement is ironic for the visitors who until then believed that a person fells more alone in a small group and that a person feels better and less alone in a very large group.
Not keeping you in
When the visitors are presented with the building where the rest of the community eats, the first thing they notice is that the building was designed in such a way as to make those eating believe they are in another country. The reason why the building was designed in such a way was to prepare the members of the community for the moment they will decide to leave and to help them adapt better to the outside world. This idea seems ironical considering the fact that Waldo Two was supposed to be a close community. Usually, those communities would do anything to keep their members from leaving but apparently that was not the case for the people in Waldo who were encouraged to go and explore the outside world.
