What are theories in social science and how it affects human behavior

It is conceivable to anticipate occasions or behaviors utilizing an arrangement of indicators, without essentially clarifying why such occasions are occurring. For example, market analysts foresee vacillations in the stock market in view of market declarations, acquiring reports of real organizations, and new data from offices, in light of beforehand watched relationships. Forecast requires just connections; explanations require causations.

Conditions to build up causation:

Correlations between two constructs
Temporal precedence
Rejection of elective speculations

Kinds of Explanations

Idiographic
Nomothetic

Idiographic Explanations
Idiographic explanations are those that clarify a solitary circumstance or occasion in idiosyncratic detail.

Example of idiosyncratic detail
A man was not doing admirably on his exam because:

He forgot that he had an exam on that day
He arrived late because of a traffic
He got terrified
He needed to work late the past night and couldn't ponder for the exam
His dog ate his reading material

The explanations might be itemized, exact, and substantial, however they may not make a difference to other comparable circumstances, notwithstanding including a similar individual, and are henceforth not generalizable.

Nomothetic Explanations
Nomothetic explanations look to clarify a class of circumstances or occasions instead of a particular circumstance or occasion. Intended to be generalizable crosswise over circumstances, occasions, or individuals, they have a tendency to be less exact, less entire, and less itemized. Be that as it may, they clarify monetarily, utilizing just a couple of logical factors. Because theories are additionally planned to fill in as summed up explanations for examples of occasions, behaviors, or phenomena, hypothetical explanations are for the most part nomothetic in nature.

Example, A man was not doing great on his exam because:

Because he didn't invest sufficient energy getting ready for exams or that he experience the ill effects of anxiety, consideration shortage, or some other medical issue.

Theory isn't

Data
Facts
Typologies
Taxonomies
Empirical discoveries

An accumulation of facts isn't a theory, similarly as a heap of stones isn't a house. In like manner, an accumulation of constructs isn't a theory, because theories must go well past constructs to incorporate suggestions, explanations, and limit conditions. Data, facts, and discoveries work at the empirical or observational level, while theories work at an applied level and depend on rationale instead of perceptions.

Advantages in utilizing theories in research

Theories give the fundamental rationale of the event of regular or social phenomenon by clarifying what are the key drivers and key results of the objective phenomenon and why, and what basic procedures are dependable driving that phenomenon.
They help in sense-making by helping us blend earlier empirical discoveries inside a hypothetical structure and accommodate conflicting discoveries by finding unforeseen components affecting the relationship between two constructs in various examinations.
Theories give direction to future research by distinguishing constructs and relationships that are deserving of further research.
Theories can add to combined knowledge building by crossing over holes between different theories and by making existing theories be reconsidered in a new light.

As disentangled explanations of reality, theories may not generally give sufficient explanations of the phenomenon of interest in light of a restricted arrangement of constructs and relationships. Theories are intended to be basic and stingy explanations, while reality might be altogether more mind boggling. Moreover, theories may force blinders or point of confinement specialists' scope of vision, making them pass up a great opportunity for vital ideas that are not characterized by the theory.
