Advantages of using the scientific method

Advantages of using the scientific method

1. EMPRICAL

   • Data = gained through direct observation, experiment of experience
     • Adavtange because.. gain concrete evidence for a theory - we can see it through people's experience
       • For example: SSRI's are tested empricially
         • Once the depressed individual has been given SSRI's, can observe their progression/ see if they improve their mood

2. OBJECTIVE

   • Advantage because.. less susceptible to bias + subjectivity
     • Getting facts means we are more certain that the data is valid
       • For example: Loftus + Palmer's experiment = objective
         • Participants were asked for estimates of speed (mph) - these numbers could not be subjected in the conclusion

3. FALSIFIABLE

   • The null hypothesis is capable of being tested + supported
     • We can test to see if a prediction of behaviour is wrong
       • For example: Loftus + Palmer's null hypothesis = leading questions will not make a difference in the pts estimates of mph
         • Using the scientific method, they were able to test this and saw that it was incorrect
       • We cannot falsify Freud's theories about the unconscious mind because we can't test them

4. CONTROLLED

   • It is Less likely that confounding variables will impact the results
     • Due to high level of control it is possible to establish cause and effect
       • Many experiments using the scientific method (Loftus + Palmer, Milgram, Acsh) would have been able to control extraneous variables such as participant differences
         • They can be sure that their findings were not affected so are valid

5. REPLICABLE

   • Makes it very reliable
     • Means other researchers can repeat the procedure + check for consistency in findings, +therefore validate previous findings
       • Asch used a standardised procedure therefore it is possible to replicate his study and test the reliability of his results
