The construction of new knowledge is a pervasive human pursuit for both individuals and collectives. From relatively simple activities such as crossing a busy road to highly complex endeavors such as launching a space shuttle, new knowledge is indispensable for secure decisions and reasoned actions. The knowledge-construction process is often involved and intricate. It draws on background notions activated from memory and local information from the immediate context. It entails the extensive testing of hypotheses and the piecing of isolated cognitive bits into coherent wholes. It integrates inchoate sensations with articulate thoughts, detects meaningful signals in seas of ambient noise, and more.
