    1. Recent work has revealed several new and significant aspects of the dynamics of theory change. First, statistical information, information about the probabilistic contingencies between events, plays a particularly important role in theory-formation both in science and in childhood. In the last fifteen years we’ve discovered the power of early statistical learning.

      The data of the past is congruent with the current psychological trends that face the education system of today. Developmentalists have charted how children construct and revise intuitive theories. In turn, a variety of theories have developed because of the greater use of statistical information that supports probabilistic contingencies that help to better inform us of causal models and their distinctive cognitive functions. These studies investigate the physical, psychological, and social domains. In the case of intuitive psychology, or "theory of mind," developmentalism has traced a progression from an early understanding of emotion and action to an understanding of intentions and simple aspects of perception, to an understanding of knowledge vs. ignorance, and finally to a representational and then an interpretive theory of mind.

      The mechanisms by which life evolved—from chemical beginnings to cognizing human beings—are central to understanding the psychological basis of learning. We are the product of an evolutionary process and it is the mechanisms inherent in this process that offer the most probable explanations to how we think and learn.

    1. One of the clear signs that the bottleneck to low-income adults working moreresults from their lack of opportunities is provided by looking at their hours of workover the business cycle. When the economy is strong and jobs are plentiful, low-incomeworkers are more likely to find work, find work with higher pay, and be able to securemore hours of work than when the economy is weak. In 2000, when the economy wasclose to genuine full employment, the unemployment rate averaged 4.0 percent and thepoverty rate was 11.3 percent; but in 2010, in the aftermath of the Great Recession, theunemployment rate averaged 9.6 percent and the poverty rate was almost 15.1 percent.What changed in those years was not poor families’ attitudes toward work but simplythe availability of jobs. Among the bottom one-fifth of nonelderly households, hoursworked per household were about 40 percent higher in the tight labor market of 2000than in recession- plagued 2010.Given the opportunity for work or additional work hours, low-income Americanswork more. A full-employment agenda that increases opportunities in the labor market,alongside stronger labor standards such as a higher minimum wage, reduces poverty.

      How can we frame the science of poverty with respect to the model of statistical mechanics?

      Unemployment numbers have very little to do with levels of poverty. They definitely don't seem to be correlated with poverty levels, in fact perhaps inversely so. Many would say that people are lazy and don't want to work when the general reality is that they do want to work (for a variety of reasons including identity and self-esteem), but the amount of work they can find and the pay they receive for it are the bigger problems.

    1. unless the model is embedded in a suitable structure thatpermits extrapolation, no useful inference is possible, either Bayesian or non-Bayesian.
