Cultural and Social Integration:
Global Collaboration: Metrics like the number of international treaties, cross-border scientific collaborations, or global initiatives (e.g., UN Sustainable Development Goals progress) reflect the noosphere's growth as a collective human endeavor. For instance, the number of countries participating in global climate agreements or the volume of cross-cultural exchanges can be tracked.
Education and Literacy: Vernadsky emphasized human reason, so global literacy rates, enrollment in higher education, or the spread of critical thinking skills are potential indicators. UNESCO data shows global literacy rates have risen to ~86% (2020), a sign of expanding cognitive capacity.
