Vom Umgang mit Schuld (2016), she philosophically explores the phenomenon of forgiveness and tells of her encounters with people who – as perpetrators or victims – are confronted with the most severe guilt.

Flaßpöhler's own story – she was abandoned by her mother at the age of fourteen and grew up with her stepfather – forms the central theme of the book, which is her most personal to date.

[4] On 1 February 2018, she appeared on the talk show Maybrit Illner and said "MeToo is of no use to women" and "The image that is produced is that of a passive woman reacting to an all-powerful phallus".

Über moderne Empfindlichkeit und die Grenze des Zumutbaren, published in 2021, Flaßpöhler explores social sensitisation and asks about the "limits of what is reasonable".

Flaßpöhler works out the progressive dynamics of historical sensitisation processes, but criticises the current tendency to want to protect the subject from all impositions as a danger to liberal society.

"[7] Flaßpöhler's demand is to add a second quality to sensitivity: resilience, which is misjudged as a neoliberal optimisation strategy, especially in left-wing circles.

In 2007, Flaßpöhler received the Arthur Koestler Prize from the German Society for Human Dying (DGHS) for her book Mein Wille geschehe.
