Krippner has made working trips to all continents of the world. His friends were such famous scientists as Abraham Maslow, Karl Rogers, Viktor Frankl, Charlotte Buehler and Fred Massarik. He is highly respected by both parapsychologists and critics of parapsychology. He is considered a friend of both the famous parapsychologist Charles Tart and the famous parapsychologist whistleblower James Randy.

And Stanley has a long-standing relationship with Russia.
Stanley Krippner began active collaboration with Soviet scientists in the early 1970s. He repeatedly visited the Soviet Union on working visits. Krippner first visited the USSR in 1971, when he came to Moscow to speak at the USSR Academy of Sciences as a representative of the Association for Humanistic Psychology. Then he devoted his report to the possible interaction of American humanistic psychology with Soviet psychology, considering the common points of view and approaches in the study of consciousness and human potential. In 1972, Krippner came to Moscow for the second time as part of a group of members of the Association for Humanistic Psychology. This meeting marked the beginning of fruitful cooperation between psychologists of the Association of Humanistic Psychology and scientists of the USSR Academy of Pedagogical Sciences (now the Russian Academy of Education). One of the results of this collaboration was the publication in 1980 of his monograph entitled "Human Possibilities: Consciousness Studies in the USSR and Eastern Europe".

After the collapse of the Soviet Union, Krippner continued to collaborate with representatives of Russian science. His publications regularly appear in leading Russian scientific publications devoted to psychology and ethnography.

In 2002, having arrived in Russia for the ninth time, Krippner took part in the X annual International Conference on conflict resolution, where he made a report on children's nightmares, which are the consequences of wartime mental trauma. This report was based on the book" The Psychological Impact of War on Civilians in an International Perspective", for which he was a co-editor.

Visiting the Department of Psychology at Sochi State University in May 2003, Krippner was surprised to see a photograph of himself along with portraits of such prominent psychologists as Stanley G. Hall, Carl Gustav Jung, Karl Buehler, and William James. In 2008, Sochi State University hosted the First All-Russian Scientific and Practical Conference " Olympic Sochi: Society. Culture. Personality", 2014 in Sochi. At the suggestion of the conference organizers, Krippner prepared a report for the conference entitled "Sports Psychology", in which he described methods for achieving high sports results.
