We reach for them mindlessly, setting our brains on auto-pilot and relaxing into the unconscious comfort of familiar routine. “Not choice, but habit rules
11、the unreflecting herd,” William Wordsworth said in the 19th century. In the ever-changing 21st century, even the word “habit” carries a negative connotation.So it seems antithetical to talk about habits in the same context as creativity and innovation. But brain researchers have discovered that when
12、 we consciously develop new habits, we create parallel synaptic paths, and even entirely new brain cells, that can jump our trains of thought onto new, innovative tracks. But dont bother trying to kill off old habits; once those ruts of procedure are worn into the hippocampus, theyre there to stay.
13、Instead, the new habits we deliberately ingrain into ourselves create parallel pathways that can bypass those old roads.“The first thing needed for innovation is a fascination with wonder,” says Dawna Markova, author of “The Open Mind” and an executive change consultant for Professional Thinking Par
14、tners. “But we are taught instead to decide, just as our president calls himself the Decider.” She adds, however, that “to decide is to kill off all possibilities but one. A good innovational thinker is always exploring the many other possibilities.”All of us work through problems in ways of which w
15、ere unaware, she says. Researchers in the late 1960 covered that humans are born with the capacity to approach challenges in four primary ways: analytically, procedurally, relationally (or collaboratively) and innovatively. At puberty, however, the brain shuts down half of that capacity, preserving
16、only those modes of thought that have seemed most valuable during the first decade or so of life.The current emphasis on standardized testing highlights analysis and procedure, meaning that few of us inherently use our innovative and collaborative modes of thought. “This breaks the major rule in the
17、 American belief system that anyone can do anything,” explains M. J. Ryan, author of the 2006 book “This Year I Will.” and Ms. Markovas business partner. “Thats a lie that we have perpetuated, and it fosters commonness. Knowing what youre good at and doing even more of it creates excellence.” This i

All tests require
24、 a potential candidate with whom to compare DNA. But some observers are skeptical, “There is a kind of false precision being hawked by people claiming they are doing ancestry testing,” says Trey Duster, a New York University sociologist. He notes that each individual has many ancestors-numbering in
25、the hundreds just a few centuries back. Yet most ancestry testing only considers a single lineage, either the Y chromosome inherited through men in a fathers line or mitochondrial DNA, which a passed down only from mothers. This DNA can reveal genetic information about only one or two ancestors, eve
26、n though, for example, just three generations back people also have six other great-grandparents or, four generations back, 14 other great-great-grandparents. Critics also argue that commercial genetic testing is only as good as the reference collections to which a sample is compared. Databases used
27、 by some companies dont rely on data collected systematically but rather lump together information from different research projects. This means that a DNA database may differ depending on the company that processes the results. In addition, the computer programs a company uses to estimate relationsh
