In spite of much documented success, PSI has not taken off massively. Education is still dominated by "same pace, different learning" approaches, and the number of new research publications about PSI gradually declined after a high in the 70's. Several possible reasons are given for this, not the least that PSI represented a too radical deviation from established teaching practices and educational management routines Sherman, J. G. (1992). Reflections on PSI: Good news and bad. Journal of Applied Behavior Analysis, 25(1), 59-64.. Other explanations include conflicts within the PSI movement and the challenge that PSI would demand more effort from teaching staffGrant , L. K., & Spencer, R. E. (2003). The personalized system of instruction: Review and applications to distance education. The International Review of Research in Open and Distributed Learning, 4(2).. However, it has been speculated that PSI might see a revival with modern educational technology, as information technology could gradually alleviate teacher burdens related to frequent testing and feedback, as well as mitigate the increased administrative complexity that  student self-pacing has over one instructor-set pace.Eyre, H. L. (2007). Keller's Personalized System of Instruction: Was it a Fleeting Fancy or is there a Revival on the Horizon?. The Behavior Analyst Today, 8(3), 317.
