Objective [Heading]	rr_ObjectiveHeading	<span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;text-transform:uppercase;">INVESTMENT OBJECTIVE</span>
Objective, Primary [Text Block]	rr_ObjectivePrimaryTextBlock	The investment objective of the Portfolio is long-term growth of capital.
Expense [Heading]	rr_ExpenseHeading	<span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;text-transform:uppercase;">PORTFOLIO FEES AND EXPENSES</span>
Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	The table below shows the fees and expenses that you may pay if you invest in shares of the Portfolio. The table does not include Contract charges. Because Contract charges are not included, the total fees and expenses that you will incur will be higher than the fees and expenses set forth in the table. See your Contract prospectus for more information about Contract charges.
Operating Expenses Caption [Text]	rr_OperatingExpensesCaption	<span style="font-family:Arial Narrow;font-size:8pt;font-weight:bold;margin-left:0.0pt;">Annual Portfolio Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)</span><span style="font-family:Arial Narrow;font-size:5pt;font-weight:bold;margin-left:0.0pt;position:relative;top:-3.25pt;">(1)</span>
Portfolio Turnover [Heading]	rr_PortfolioTurnoverHeading	<span style="font-family:Arial;font-size:10pt;font-weight:bold;">Portfolio Turnover. </span>
Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in annual portfolio operating expenses or in the example, affect the Portfolio's performance. During the Portfolio's most recent fiscal year ended December 31, the Portfolio's portfolio turnover rate was 41% of the average value of its portfolio.

Expenses Restated to Reflect Current [Text]	rr_ExpensesRestatedToReflectCurrent	<span style="font-family:Arial Narrow;font-size:8pt;">Any differences in total annual portfolio operating expenses shown in the table above and the expense ratio (after waivers and/or reimbursements) in the Portfolio’s Financial Highlights are attributable to changes in management fees, fee waivers and/or expense limitations occurring after the end of the most recent fiscal year.</span>
Expense Example [Heading]	rr_ExpenseExampleHeading	<span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;">Example. </span>
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	The following example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The table does not include Contract charges. Because Contract charges are not included, the total fees and expenses that you will incur will be higher than the fees and expenses set forth in the example. See your Contract prospectus for more information about Contract charges.The example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Portfolio’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Portfolio invests its assets primarily in equity and equity-related securities in an allocation that is substantially similar to the composition of the Portfolio’s benchmark, the MSCI World Index (GD). The Portfolio invests primarily in common stocks (and their equivalents) of foreign and US companies. The Portfolio has multiple subadvisers and each subadviser uses either a “growth” approach or a “value” approach in selecting either foreign or US equity or equity-related securities.In pursuing its value strategies, the Portfolio seeks to invest in undervalued stocks that have high near-term appreciation potential. In addition, the Portfolio seeks to invest in undervalued large companies that provide good prospects for capital appreciation, although such companies may temporarily be out of favor. The Portfolio may, at times, also invest significantly in certain sectors.In pursuing its growth strategies, the Portfolio relies on fundamental research to identify and invest in foreign and US companies with market capitalizations over $100 million that appear to have above-average prospective growth potential, evidence of sustainability of future growth, above-average profitability and reinvestment of internal capital, as well as a conservative capital structure.

Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The bar chart and table provide some indication of the risks of investing in the Portfolio by showing changes in the Portfolio's performance from year to year and by showing how the Portfolio's average annual returns for 1, 5, and 10 years compare with those of a broad-based securities market index that reflects the performance of the overall market applicable to the Portfolio.Past performance does not mean that the Portfolio will achieve similar results in the future.The annual returns and average annual returns shown in the chart and table are after deduction of expenses and do not include Contract charges. If Contract charges were included, the returns shown would have been lower than those shown. Consult your Contract prospectus for information about Contract charges.Annual return information in the bar chart is provided only for Class I shares. Because all of the Portfolio’s shares are invested in the same portfolio of securities, annual returns for Class III shares would be lower because Class III shares do not have the same expenses as Class I shares.

PSF Global Portfolio | Risk Lose Money [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	The relative significance of the risks summarized below may change over time. All investments have risks to some degree, and it is possible that you could lose money by investing in the Portfolio.
PSF Global Portfolio | Risk Not Insured Depository Institution [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	An investment in the Portfolio is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
PSF Global Portfolio | Equity Securities Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Equity Securities Risk. The value of a particular stock or equity-related security held by the Portfolio could fluctuate, perhaps greatly, in response to a number of factors, such as changes in the issuer’s financial condition or the value of the equity markets or a sector of those markets. Such events may result in losses to the Portfolio. In addition, due to decreases in liquidity, the Portfolio may be unable to sell its securities holdings within a reasonable time at the price it values the security or at any price.
PSF Global Portfolio | Foreign Investment Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Foreign Investment Risk. Foreign markets tend to be more volatile than US markets and are generally not subject to regulatory requirements comparable to those in the US. Foreign securities include investments in securities of foreign issuers denominated in foreign currencies, as well as securities of foreign issuers denominated in US dollars and American Depositary Receipts. Foreign investment risk includes the risk that: changes in currency exchange rates may affect the value of foreign securities held by the Portfolio; foreign markets generally are more volatile than, and generally are not subject to regulatory requirements comparable to, US markets; foreign financial reporting and tax standards usually differ from those in the US; foreign exchanges are often less liquid than US markets; political or social developments may adversely affect the value of foreign securities; foreign holdings may be subject to special taxation and limitations on repatriating investment proceeds; and certain events in foreign markets may adversely affect foreign and domestic issuers, including, among others, military conflict, geopolitical developments, interruptions in the global supply chain, natural disasters, and outbreaks of infectious diseases.
PSF Global Portfolio | Focus Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Focus Risk. The Portfolio focuses or may focus its investments in particular countries, regions, industries, sectors, markets, or types of investments and may accumulate large positions in such areas. As a result, the Portfolio invests in the securities of a small number of issuers and has greater exposure to adverse developments affecting those issuers and a resulting decline in the market price of those issuers’ securities as compared to a portfolio that invests in the securities of a larger number of issuers.
PSF Global Portfolio | Quantitative Model Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Quantitative Model Risk. The Portfolio and certain underlying portfolios, if applicable, may use quantitative models as part of their investment process. Securities or other investments selected using quantitative methods may perform differently from the market as a whole or from their expected performance for many reasons, including factors used in building the quantitative analytical framework, the weights placed on each factor, and changing sources of market returns. There can be no assurance that these methodologies will produce the desired results or enable the Portfolio to achieve its objective. A given model may be more effective with certain instruments or strategies than others, and there can be no assurance that any model can identify and incorporate all factors that will affect an investment’s price or performance. When models prove to be incorrect or incomplete, including because data is stale, missing or unavailable, any decisions made in reliance thereon expose the Portfolio to potential risks. Models rely on correct data inputs. If incorrect data is entered into even a well-founded model, the resulting information will be incorrect.
PSF Global Portfolio | Blend Style Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Blend Style Risk. A Portfolio's blend investment style may subject the Portfolio to risks of both value and growth investing. The portion of the Portfolio's portfolio that makes investments pursuant to a growth strategy may be subject to above-average market price fluctuations as a result of seeking high-quality stocks with good future growth prospects. The portion of the Portfolio's portfolio that makes investments pursuant to a value strategy may be subjectto the risk that the market may not recognize a security's intrinsic value for long periods of time or that a stock judged to be undervalued may actually be appropriately priced. Issuers of value stocks may have experienced adverse business developments or may be subject to special risks that have caused the stock to be out of favor. If the Portfolio's assessment of market conditions or a company’s value is inaccurate, the Portfolio could suffer losses or produce poor performance relative to other funds. Historically, growth stocks have performed best during later stages of economic expansion and value stocks have performed best during periods of economic recovery. Therefore, both styles may over time go in and out of favor depending on market conditions. At times when a style is out of favor, that portion of the portfolio may lag the other portion of the portfolio, which may cause the Portfolio to underperform the market in general, its benchmark, and other mutual funds.
PSF Global Portfolio | Economic And Market Events Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Economic and Market Events Risk. Economic and market events risk is the risk that one or more markets in which the Portfolio invests will decline in value, including the possibility that the markets will decline sharply and unpredictably. While a Portfolio’s Manager or Subadviser(s) may make efforts to control the risks associated with market changes, and may attempt to identify changes as they occur, market environment changes can be sudden and extreme. Significant shocks to or disruptions of the financial markets or the economy, including those relating to general economic, political, or financial market conditions; significant or unexpected failures, near-failures or credit downgrades of key institutions; investor sentiment and market perceptions; unexpected changes in the prices of key commodities; government actions; geopolitical events or changes; and factors related to a specific issuer, geography, industry or sector, could adversely affect the liquidity and volatility of securities held by the Portfolio. In periods of market volatility and/or declines, the Portfolio may experience high levels of shareholder redemptions, and may have to sell securities at times when it would otherwise not do so, and at unfavorable prices.
PSF Global Portfolio | Expense Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Expense Risk. The actual cost of investing in the Portfolio may be higher than the expenses shown in the “Annual Portfolio Operating Expenses” table above for a variety of reasons, including, for example, if the Portfolio’s average net assets decrease.
PSF Global Portfolio | Investment Style Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Investment Style Risk. Securities held by the Portfolio as a result of a particular investment style, such as growth or value, tend to perform differently (i.e., better or worse than other segments of, or the overall, stock market) depending on market and economic conditions and investor sentiment. At times when the investment style is out of favor, the Portfolio may underperform other funds that invest in similar asset classes but use different investment styles.
PSF Global Portfolio | Large Company Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Large Company Risk. Large-capitalization stocks as a group could fall out of favor with the market, causing the Portfolio to underperform investments that focus on small- or medium-capitalization stocks. Larger, more established companies may be slow to respond to challenges and may grow more slowly than smaller companies.
PSF Global Portfolio | Liquidity And Valuation Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Liquidity and Valuation Risk. The Portfolio may hold one or more securities for which there are no or few buyers and sellers or the securities are subject to limitations on transfer. The Portfolio may be unable to sell those portfolio holdings at the desired time or price, and may have difficulty determining the value of such securities for the purpose of determining the Portfolio’s net asset value. In such cases, investments owned by the Portfolio may be valued at fair value pursuant to policies and procedures adopted and implemented by the Manager. No assurance can be given that the fair value prices accurately reflect the value of the security. The Portfolio is subject to a liquidity risk management program, which limits the ability of the Portfolio to invest in illiquid investments.
PSF Global Portfolio | Market And Management Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Market and Management Risk. Markets in which the Portfolio invests may experience volatility and go down in value, and possibly sharply and unpredictably in short periods of time. Investment techniques, risk analyses, and investment strategies, which may include quantitative models or methods, used by a subadviser in making investment decisions for the Portfolio are subject to human error and may not produce the intended or desired results. The value of the Portfolio’s investments may be negatively affected by the occurrence of domestic or global events, including war, terrorism, environmental disasters, natural disasters, sanctions, cybersecurity events, supply chain disruptions,political or civil instability, and public health emergencies, among others. Such events may reduce consumer demand or economic output, result in market closures, travel restrictions or quarantines, and significantly adversely impact the economy. There is no guarantee that the investment objective of the Portfolio will be achieved.
PSF Global Portfolio | Mid Sized Company Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Mid-Sized Company Risk. The shares of mid-sized companies tend to trade less frequently than those of larger, more established companies, which can have an adverse effect on the pricing and volatility of these securities and on the Portfolio’s ability to sell the securities.
PSF Global Portfolio | Regulatory Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Regulatory Risk. The Portfolio is subject to a variety of laws and regulations which govern its operations. The Portfolio is subject to regulation by the Securities and Exchange Commission (the SEC), and depending on the Portfolio, the Commodity Futures Trading Commission (the CFTC). Similarly, the businesses and other issuers of the securities and other instruments in which the Portfolio invests are also subject to considerable regulation. Changes in laws and regulations may materially impact the Portfolio, a security, business, sector, or market.
