Personalitytests can either be objective or subjective. There are severalfactors that influence the choice of the type of test adopted.Objective personality tests are very common among psychologistsbecause they are cost effective and reliable. This is one of themajor advantages of objective tests. This is because the testinvolves fixed questions that can be administered at the testadministrator and test taker convenience. Objective tests can alsouse technologies such as computer and internet or administer the testto a group of subjects. This saves time and cost. Additionally, thedata collected is easier to interpret and analyze. Additionally, theobjectivity in the tests eliminates the likelihood of biasness in thetests. Majority of the questions are true or false questions whicheliminates the influence of the test administrator in the test. Thiseliminates the ethical issues that are associated with biasness,profiling, and prejudice in psychological tests (Carducci, 2006).
However,there are some disadvantages of objective personality test. Thisdisadvantage has an impact on reliability and ethical standards ofthe results of obtained. For example, in objective personality tests,there is a likelihood of the respondent faking responses or givinganswers that are not genuine. Although there are new versions ofobjective tests that eliminates the fake responses and increase itsvalidity, fake answers is an important concern for major objectivetests. Another major disadvantage of objective tests is the fact thatthe scoring in the response is limited. This is because one score isgiven for a range of questions that cover different behaviors andcognitive abilities. Since the scoring is limited, the interpretationof the results is also limited (Carducci, 2006).
