How Much Information? How Much Information? 2009 Report on American Consumers (PDF) Date of Publication: December 2009 Last Update: January 2010 Executive Summary In 2008, Americans consumed information for about 1.3 trillion hours, an average of almost 12 hours per day. Consumption totaled 3.6 zettabytes and 10,845 trillion words, corresponding to 100,500 words and 34 gigabytes for an average person on an average day. A zettabyte is 10 to the 21st power bytes, a million million gigabytes. These estimates are from an analysis of more than 20 different sources of information, from very old (newspapers and books) to very new (portable computer games, satellite radio, and Internet video). Information at work is not included. We defined "information" as flows of data delivered to people and we measured the bytes, words, and hours of consumer information. Previous studies of information have reported much lower quantities. Despite this, computers have had major effects on some aspects of information consumption.
PKM and Information Overload. Jason Frand and Aura Lippincott February 4, 2002 DRAFT Introduction Personal Knowledge Management (PKM) was developed as a workshop for students in MBA programs at The Anderson School at UCLA. The Anderson School's MBA programs present significant challenges to incoming students: a heavy workload, limited time, extensive and diverse informational resources, and an advanced technological environment that includes a laptop requirement for each entering student. PKM is a strategy for managing your information in our thethis information intense environment of todays society where information overload is an intrinsic problem.
(endnote: For the purposes of this paper, we will consider data, information, knowledge and wisdom as different. Dimensions of Information OverloadThe modern information society Although a novel approach for dealing with information overload is presented here, the problem has been recognized for a long time. Defining information overload Impacts of information overload II.
Personal knowledge management & wisdom. PKM consists of practical methods for making sense of the increasing digital information flows around us. There is no procedural method to go from data to wisdom. On this Stephen Downes and I agree; though he thinks I adhere to the DIKW model. That said, while this is a much better model than this, I think it stays true to the original ‘filtering’ vision, where you go from data to wisdom through successive filtering processes. And while there are different ways to think of knowledge – processed, procedural, propositional – this model I think adheres to a more basic view. Here are some images from a presentation on PKM I will be giving at our local university tomorrow and including in a workshop next week. Data does not create information; information does not create knowledge and knowledge does not create wisdom. People use their knowledge to make sense of data and information. Data + Knowledge = Information Seek, Sense, Share: Find.
