orient主要是adjust something to a specifc position or direction,引申表达有make sb familiar with sth,这里你可以理解为focus,或者propensity,inclination等等,bias这个词,不要狭义地理解为prejudice,广义的含义是take a side from two or more options.
bias:a strong interest in sth or ability to do sth,这个是韦氏的解释。
同问!orientation有这些意思:
---the act of orienting
an integrated set of attitudes and beliefs
---position or alignment relative to points of the compass or other specific directions
---a predisposition in favor of something
showed a Marxist orientation
synonymous: predilection, preference
---a person's awareness of self with regard to position and time and place and personal relationships
---a course introducing a new situation or environment
感觉如果要解释的话就是第二或者第三个解释,但仍然是orientation towards sth是褒义的,同义词preference 的话。
