In the City of Elpis, in the year 2100, there has been a reality revolution. Prior to the revolution, Elpis citizens were unable to see their flaws and limitations, believing themselves talented and special. This led to a self-absorbed society in which hard work and the collective good were undervalued and eroded. To combat this, Professor Milton Grey invented the reality prism, a hat that allowed its wearers to see themselves as they really were – flaws and all.
Faced with the truth, Elpis citizens revolted and destroyed and banned all reality prisms. Zach and Alice are born soon after all the prisms have been destroyed. Zach, a musician who doesn’t understand science, and Alice, a geneticist who is also a whiz at statistics, are in love. One night, after making a world-changing discovery, Alice suddenly disappears, leaving behind a song playing on a loop and a file with her research on it. Sensing that she might be in danger, Zach follows the clues to find her, as he realizes that the key to discovering why Alice has vanished is in her research. He must learn statistics and apply what he learns in order to overcome a number of deadly challenges and find the love of his life. Ancient Indian Leaps into Mathematics by: B.

Covey Almost everywhere we turn, trust is on the decline. We find low trust in our society at large, in our institutions and in our companies. Covey Increasingly, more leaders are discovering trust as they begin to see it with new eyes. Looking beyond the common view of trust as some soft, intangible and illusive social virtue, they’re learning to see it as a critical, highly relevant and tangible asset. Global Retail Organization: Dramatically improved the accuracy of their inventory projections.
Training Summary Inspiring Trust teaches those in leadership positions why building a high-trust work environment must be as essential as any other measurable economic goal of the organization and is the foundation to leadership. Simply open the box, take out the fun and engaging materials and begin. Your Trust Quotient, or tQ score, is an indicator of the level of trust others have in you. Sample This is an employee survey – a cultural audit, used before, during and after a learning process.
Besides understanding the current trust levels, it identifies specific behaviors that are creating the trust level. Sample The Speed of Trust Team index is a powerful tool for teams.

We’re dedicated to improving science instruction and increasing public awareness of science education. A growing proportion of human activities, such as social interactions, entertainment, shopping, and gathering information, are now mediated by digital services and devices.
We distinguish between data that are actually recorded and information that can be statistically predicted from such records. People may choose not to reveal certain pieces of information about their lives, such as their sexual orientation or age, and yet this information might be predicted in a statistical sense from other aspects of their lives that they do reveal. This study demonstrates the degree to which relatively basic digital records of human behavior can be used to automatically and accurately estimate a wide range of personal attributes that people would typically assume to be private. The design of the study is presented in Fig. As a consequence, their values can only be measured approximately, for example, by evaluating responses to questionnaires. The transparent bars presented in Fig. Thus, although the SWL score includes variability attributable to mood, users’ Likes accrue over a longer period and, so, may be suitable only for predicting long-term happiness.
Amount of Data Available and Prediction Accuracy. The results presented so far rely on individuals for which between one and 700 Likes were available. Therefore, what is the expected accuracy given a random individual and how does prediction accuracy change with the number of observed Likes? Accuracy of selected predictions as a function of the number of available Likes. Individual traits and attributes can be predicted to a high degree of accuracy based on records of users’ Likes. Table S1 presents a sample of highly predictive Likes related to each of the attributes.
