Thought privacy, that is, the right to control who has access to one’s thoughts, is a bedrock of human civilization as we know it today. Lie detection technologies, with their severe limitations, have proliferated in use all over the world. Such unsupervised proliferation of technology that claims to infer human psychological states has huge implications for the future of human existence and rights. We collate data about usage of lie detection technologies for six categories of use in all sovereign countries of Asia, Africa and Europe. The collected data, being category specific, also provides insight into what kind of uses are more prevalent. The present paper provides an idea about the enormity and spread of the problem of lie detection technology proliferation. We also provide observations about legal control mechanisms of such issues. This data provides a baseline for further observation and monitoring of the field of lie detection technology proliferation.
